"Naka," it was the beginning in a submarine career through an expulsion corps, the "crescent moon" gunnery head to have become "呂 65" member of crew. I am promoted to (1931), a captain in 1931 and take a mine school advanced course student. The line officer finished officer education in the advanced course of the technical school if usual, but Kusaka advanced to the diving school second that was a submarine mine long training course [5] through "Italy 57" chief navigator. It is placement that the submarine mine head assists the diving captain as a senior officer and commands submarine voyage work [5]. "Italy 24" successively held the mine head by three warships of "Italy 2" "Italy 68", and Kusaka assisted Shinji Uchino. Kusaka promoted to a major (1939) in March in 1939 is appointed the "Italy 121" diving captain which is a mining submarine, and subsequently it is a diving school first grade student. This course trains the diving captain and almost wears learning, the ability that are necessary as the tactics, a voyage, [5], the diving captain including the weapon in a period of a half year. After graduation, I made the outbreak of war of the Pacific War the captain of "呂 63" which was an L four type second prize submarine through the "呂 58" diving captain.
"呂 63" was one warship of the 33rd diving corps to belong to the fourth fleet (Narumi Inouecommander in chief) seventh diving squadron (CommanderShinzo Onishi) which guarded the South Seas in by an old submarine. The diving captain of the sister ship had Yasuo Fujimori in charge of Operation submarine in the Naval General Staff [6]. I watched Howland Island with sister ship on the occasion of Pearl Harbor attack. This island was staging base when US Navy went from Hawaii into the South Pacific [7]. I turn to the "Italy 174" diving captain of the third diving squadron (三輪茂義司令官) eleventh diving corps position (1942) in March in 1942.
Captain Italy 174 diving
I made a sortie south on April 15, but the Tokyo area receives bombing on 18th, and Kusaka is ordered the pursuit of the U.S. carrier. The Japanese Navy submarine corps was not able to discover an enemy corps, but Kusaka discovered "the first rock hand lantern". "The first rock hand lantern" was discovered in the U.S. military unit by one ship of the placed monitoring boat corps for the enemy corps who planned an approach in Japan and suffered damage by machine-gun mopping-up. I save a crew and send Kusaka to "Kiso" [7]. Patrol deployment wanted to have the third diving squadron until 27th, and [8] suffered from the Commander Miwa Kawano 10 million castle and a change because of a disease [9]. I participated in the Battle of Midway, and the third diving squadron repeated the change of the cordon during sea fight, but "Italy 168" (Captain Yahachi Tanabe) about the independent duty attacked and sank "Yorktown". Next "Italy 174" returns to Kure according to enemy reinforcement block in the south in [10], November [11].
Captain Italy 180 diving
On December 1, I am appointed the "Italy 180" equipment officer head of the Araumi large size and take office as the first captain after the completion. "Italy 180" is admitted into the 22nd diving corps of the third diving squadron (Commander Katsumi Komazawa) position [12] and follows the traffic destruction round (1943) at the Australia east coast from April in 1943. There is Kusaka between Sydney, Brisbane with "Italy 180" and attacks and sinks two ships (4,376t in total) and overthrows two (7,013t) and saves 21 crews of "the divine power" attacked and sunk by Colombin Gullah island offing sea fight again [7]. Succeeded in transportation to ラエ in the submarine transportation on August 4 [7]; [13].
Captain Italy 26 diving
Having taken up the post formerly captain Minoru Yokota of "Italy 26." Yokota is converted to Christianity after the war, too.
In September, I become the "Italy 26" diving captain. "Italy 26" is the distinguished military service warship which gave military gains such as the "Saratoga" falling of a thunderbolt, the "Juneau" sinking [7]. The warship becomes the admission in the eighth diving squadron (Commander Ichioka Kotobuki)) and engages in the Indian Ocean, a traffic destruction war in the Arabian Sea. Kusaka attacked and sank "Albert Galant Japanese spaniel" (7,176t) at "tones" (8,054t) by the strategy in the Indian Ocean area (1944) on January 1 each overthrowing, 1944 on "Robert T hawk" (7,176t), December 31 on October 28 [7]. Then, I moved to a strategy in the Arabian Sea and included military gains of the overthrowing at "Glenat" (8,117t) (7,176t) "Richard ホベイ" on each sinking, March 29 on "Collier" (8,298t), March 21 on March 13 [7]. In addition, I engage in a strategy to let an agent infiltrate in the India country [14]. This agent was aimed for the India independence by the person from India which a light organization trained, inside work [15] and was carried out for three times, and I hit it, and "Italy 26" of Kusaka was in charge of twice. I let Kusaka comes close near the land of India, and 18 agents infiltrate. Staff Officer predecessor of the eighth diving squadron, Shojiro Iura nominates the ability of Kusaka for a reason of the success [15].
Kusaka who returned to Kure in May was ordered transportation to Saipan. The Japanese Navy which lost a carrier force by Mariana Islands offing sea fight planned the force reinforcement of Mariana Islands, and "Italy 26" left for Saipan. However, I am going on a voyage, and the destination is changed to Guam and succeeds in the transportation of the arsenal to July 9 [16]. Four submarines engaged in this transportation operation, but it is "Italy 26" of Kusaka to have succeeded [7]. "Italy 26" was ordered the crew accommodation from the Tinian island more, but there was already the island for the close siege of the alliance national military and was not able to accommodate it. Kusaka criticizes the navy upper echelon about the order at the point in time that this Saipan fall, Tinian are just before the fall [7].
Captain Italy 400 diving
"Italy 400" crew. As for Kusaka, a lot of inexperienced people of the submarine repeated a basic trainning [17].
Kusaka does 退艦 in August and is appointed the "Italy 400" submarine equipment officer head. Cruising power [18] that could make a round trip from Japan to every points of the world was equipped with water air raider "haze" three again without refueling it in big warship [* 1] where it was the same level as a light cruiser of reserve displacement 5,223t, and "Italy 400" had aerial reconnaissance ability. There were twists and turns over the building of this warship, but I constituted "Italy 14" and a first diving corps [19], and training was carried out with Riyunosuke Ariizumi commander other than same model warship "Italy 401" (Captain Nobukiyo Nanbu) "Italy 13". The first diving corps was changed in the task force where Okinawa round began, and [20] did the target in the Woolsey atoll in a living-in-night intended that suicide attack によって destroyed Panama Canal with ten haze. As for August 17 [21], the strategy name, storm operation, the strategy corps named a submarine corps, an aviation corps generally (1945) in 1945 on scheduled enforcement date of this strategy and were named Ryu God special attack unit [22]. Kusaka made a sortie against [* 2] in large Minato on July 23 and went to the Woolsey atoll.
"Italy 13" had just made a sortie by this military manoeuvre and has not been heard of, and Mrs. newly-married senior officer commits suicide [23]. While "Italy 400" arrived at it near Woolsey atoll on August 14 and planned assembly with "Italy 401", I received the telegram which meant the Potsdam Declaration acceptance of Japan. Kusaka accepts advice of the mine head and tells a subordinate about war end. The "Italy 400" crew faced reality called the defeat of Japan in front of suicide attack を, but the later action was serenity [24]. Kusaka carried out a radio blockade and I took the detour route and started on the return. It was choice of Kusaka that the possibility that this route was struck considered. Kusaka bore tears when I was captured by the US Navy corps, and a naval ensign was replaced to the Star-Spangled Banner [25].
Postwar
I was accused of a BC grade war crime about the allied powers sailor killing case by the submarine corps in the Indian Ocean area and was sentenced to hard labor five years [26]. An arrest, prosecution [27] were considered to be it, and, by this case, a person concerned with navy, Teruhisa Komatsu, Hisashi Mito, Ichioka Kotobuki, Shojiro Iura, the diving captain who obeyed a traffic destruction war in the Indian Ocean contributed to the war crime prosecution of combined fleet commander in chiefSoemu Toyoda [28]. [26][* 3] where Kusaka speaks own purity about this matter saying "a piece of guilty place is few innocence." Kusaka was converted to Christianity behind bars [26], and the "Italy 400" crew continued associating for a long time after the war around Kusaka. Kusaka was a man of integrity, and I was loved by a subordinate [29].

With Sender Policy Framework (sender policy framework), it is one of the transmission domain certification in the E-mail. It is a technique to detect whether the e-mail address of the sender does not pretend to be other domain names. I am called SPF or the SPF certification.
Table of contents
Summary
"The SMTP" used for an E-mail in the Internet can give its all the e-mail addresses of the sender freely. Because these spread as a virtual standard, I will come to the front as a security hole. An unwanted e-mail sender, the falsification of the sender address by so-called "spammer" were carried out in all parts of the world and were able to in this way trouble a user.
Therefore the discussion gradually got into full swing, and SPF came up as one of the measures. The falsification of the IP address is devised based on a premise to be difficult, and this can complete the certification just to acquire information listed on the principle DNS server. I can implement it easily to make the SPF-adaptive domain that I did by adding a postscript to the sentence structure called the SPF record for the zone file in the DNS server which the domain belongs to.
The SPF cannot defend all unwanted e-mails. Because it is "to detect whether I read a domain name listed in a sender address, and it is transmitted by a right email server" that SPF performs, I cannot detect the unwanted e-mail that does not falsify a sender address although there is an effect for the phishing that went by way of the E-mail which, for example, pretended to be domains such as a big company or the government. In addition, I cannot detect it in the SPF when I falsify only an account part, and the email transmission is possible in the same domain.
However, correspondence on the domain owner side may be relatively easy, and the SPF may say that the spread advances. In Japan, I am provided as one of the filtering services used by an E-mail led by a cell-phone company and it is called "spoofing attack email measures" other than "the domain certification" and spreads rapidly.
SPF record
The SPF is determined in RFC 7208, and the specifications are shown.
I show the general contents of the SPF record. I will declare the domain that the following contents were appointed saying "I want you to trust an E-mail sent by the IP address band which I appointed, but want you to refuse the E-mail from other IP address".
I really show the general contents of the zonal file which reflected an SPF record. I will declare the domain that the following contents were appointed saying "I want you to trust the E-mail sent by 203.0.113.1 or 203.0.113.2, but the E-mail from other IP address wants you to refuse it".
: : IN MX 10 mail IN TXT "v=spf1 +ip4:203.0.113.1 +ip4:203.0.113.2 -all" IN A 203.0.113.1 mail IN A 203.0.113.2 : :
It is recommended that I put the SPF record in less than 450 characters to maintain the compatibility with the old DNS server, but the TXT record of the DNS server needs attention in only 255 characters being able to fill it out per one. When there are a great many IP address bands sending an E-mail as an example and exceeds 255 characters, I close ダブルクウォート in the middle of a record as follows, and it is necessary to describe it while dividing it. I am just coupled, and the divided part is interpreted by a DNS server.
: : IN MX 10 mail IN TXT "v=spf1 " "+ip4:203.0.113.0/28 +ip4:198.51.100.64/28 +ip4:192.0.2.16/28 " "+ip4:203.0.113.128/28 +ip4:198.51.100.96/28 +ip4:192.0.2.48/28 " "+ip4:203.0.113.144/28 +ip4:198.51.100.128/28 +ip4:192.0.2.160/28 " "+ip4:203.0.113.160/28 +ip4:198.51.100.160/28 +ip4:192.0.2.176/28 " "+ip4:203.0.113.192/28 +ip4:198.51.100.192/28 +ip4:192.0.2.240/28 " "-all" IN A 203.0.113.1 mail IN A 203.0.113.2 : :
The domain that the following contents were appointed will declare, "I follow the description of the SPF record appointed in sp.example.jp and sp.example.com". I mention it later, but an item except ip4 ip6 all must not be beyond ten in 1 record.
: : IN MX 10 mail IN TXT "v=spf1 +ip4:203.0.113.2 include:sp.example.jp include:sp.example.com -all" IN A 203.0.113.1 mail IN A 203.0.113.2 : :
The machine admitted that the SPF sends the E-mail for a certain domain formally makes it possible that a domain owner exhibits a thing (following sender policy) called one in TXT record of the DNS using an exclusive format. For example, as for the machine which does not admit that a sender address sends the E-mail which is over in "... @example.jp" formally, "example.jp" owner can appoint a thing called one. The delivery email server to inspect SPF can refuse the E-mail which arrived from a machine without authority before receiving the correspondence of the E-mail. Therefore, the theory is totally similar to the thing with the DNS blacklist (DNSBL: DNS-based Blackhole List) except that SPF uses authority commission of true Domain Name System.
The SPF protects an e-mail address of Return-Path which is the 'notify' party of the error email. I am informed the sender address in a beginning starting communication by the SMTP. The transmission former email server without the authority should send an error email to the e-mail address when transmission email server refuses the sender address. You should insert Return-Path header when transmission email server receives the sender address and accepts an address e-mail address and the correspondence successively again to maintain a sender address. The e-mail address of Return-Path often fits the sender e-mail address of the email header such as "From:" and "Sender:", but that's why there is not necessarily it. In addition, SPF is not a thing preventing these e-mail address falsification.
The spammer has the account of the domain that sender policy is listed in and can send an E-mail to do that I pass (Pass) to inspection of the SPF by misusing the system which became the crisis under the domain. In addition, it can send an E-mail passing inspection of the SPF to registered user even to go by way of an unjust certification server providing service letting the SPF certification from any sender address pass it. However, the unwanted e-mail made in that way can identify a transmission former email server easily.
The main advantage of the SPF is brought by the people whom an e-mail address is used for for falsification of Return-Path. Enormous error emails and other automatic reply emails that they do not ask for are sent, and they make it hard for it to use the E-mail commonly. If such people exhibit all IP addresses except it which performs failure (Fail) in inspection in an SPF record with a regular transmission IP address, delivery ahead email server to inspect SPF becomes able to refuse a falsification email, and the gross weight of the backscattering email decreases.
The SPF may bring profit more than a level to help the identification of the unwanted e-mail. When a sender in particular offers SPF information, I am connected and can use the result that the delivery email server passed inspection of the SPF for a white list to distinguish a known reliable sender. However, something like system and joint ownership email transmission system which became a crisis will limit this how to use.
Inspection failure and email transfer
When I declare the SPF record that a certain domain fails inspection, it is transmitted by the domain, and delivery is refused on the following conditions, and an error response can have possibilities to be returned to the fair E-mail which was transferred from delivery email server to a third party. (1)Unlike a mailing list, it is a characteristic of the SPF which the (3) forwarding address email server which does not exist is necessary for this inspecting SPF, and a transfer cause email server does it in a list of white of the (2) forwarding address email server which a transfer former email server does not transfer Return-Path to, and is clear. "Border" email server (behind email essence changer 〈 MX 〉), I cannot inspect SPF directly.of the delivery
The person with declaration becoming unacceptable as inspection of the SPF must accept a potential problem. They cannot demand that all delivery email server changes the transfer processing. In other words, one is clear in three at least serious conditions described here.
Technique called sender re-writing scheme (SRS) is a method for email transfer service to evade this problem.
HELO examination
For empty Return-Path used by an error email and other automatic reply emails, it may be said that SPF inspection by the HELO identity is almost duty. In "HELO mail.example.jp" and "EHLO mail.example.jp," I really inspect "postmaster@mail.example.jp" artificially.
The result that there is no SPF in (None) is useless in the false HELO identity, but, for effective host name, the SPF protects HELO identity. It was always coped as a choice for delivery email servers, and the last specifications that it was recommended that I always inspected HELO were included in the characteristic of this SPF with the later SPF draft again.
This enables it to refuse the white list of transmission former email servers based on passing HELO and all email servers failing HELO again. I can be used for a rating (レピュテーション) system. (a list of white and the blacklist are simple examples of the rating system)
Implementation
The implementation of the SPF consists of two parts.
I identify the email server which I recognized formally because a domain sends an E-mail on behalf of them. The domain adds this addition information to their existing DNS information. The delivery email server requires SPF information and can use it. As for the email server, it is generally done a cache for a performance enhancement of the DNS using a usual DNS inquiry. The delivery email server interprets information listed in SPF and acts according to the result.
In this way, specifications of the new DNS information that a domain sets it, and delivery email server uses are the core of the SPF. The SPF record is set in a standard DNS sentence structure as follows. example.jp. IN TXT "v=spf1 a mx -all"
"v=" defines the version of the used SPF. The following words prescribe mechanism (Mechanism) to use to be decided whether there is the qualification that a certain domain sends an E-mail to. "a" and "mx" show a computing system allowed to send an E-mail for a predetermined domain. If a previous system does not agree, "-all" in the last of the SPF record shows that the message should be refused.
Mechanism
Eight mechanism is defined.
all
It is always the truth. As a result of being established, I am used for mechanism to take first priority for all IP addresses not to accord like "-all".
a
When a domain name has A record (or AAAA record for IPv6) fitting it in the IP address of the transmission former email server, it becomes the truth (in other words, the E-mail arrives from a direct domain name).
ip4
When a transmission former email server is in the appointed IPv4 address range, it becomes the truth.
ip6
When a transmission former email server is in the appointed IPv6 address range, it becomes the truth.
mx
When a predetermined domain name has MX record tied to the IP address of the transmission former email server, it becomes the truth (in other words, the E-mail arrives from one of email servers of the domains).
ptr
When and I reverse pull that (Forward Confirmed reverse DNS), the IP address of the origin of transmission email server are included in the result that pulls plus, and did the reverse pull domain for the IP address of the transmission former email server, and a domain is over in an appointed domain name, it is the truth.
exists
I perform an original pull in a predetermined domain name and become the truth in the presence of A record (regardless of the IP address).
This is hardly used only with an SPF macro language to use for more complicated collation like DNSBL.
include
I take in a predetermined policy and become the truth when it passes inspection of the SPF. This is used normally to take in the policy of plural ISPs.
Limited child
I can associate each mechanism with one among four limited children.
"+" means a pass (Pass) of the inspection. I am used for an existing set price when I omitted a limited child, and "mx" is equal to "+mx".
I mean neutrality (Neutral) of the は inspection. When a policy is not appointed, I am interpreted like (NONE).
"~" means weak failure (SoftFail). It helps debug it between neutrality (Neutral) and failure (Fail).
"-" means failure (Fail). The E-mail should be refused (see below).
Modifier
The modifier considers future expansion of the SPF. So far, about two modifiers determined in RFC 7208, it was unfolded widely.
"exp=some.example.jp" gives a domain name in TXT record of the DNS. It is interpreted using a macrolanguage of the SPF to get explanation (generally a URL) of the failure (Fail) in addition to an SMTP error code. Most of these functions decorative excessively are not employed.
Instead of tying "all" to the SPF record of other domains, I can use "redirect=some.example.jp". It is easy how much this modifier is than I understand "include" which is similar mechanism.
Error processing
When SPF implementation detects the grammar error of the SPF record, you must stop an evaluation as a lasting error (PermError) promptly. The result cannot expect that I skip mechanism taking the wrong and continue it. Therefore, "include:bad.example" and "redirect=bad.example also" become "PermError".
As other safety measures, mechanism to refer to DNS namely every mechanism except "ip4" "ip6" "all" is limited by up to ten per SPF record. When an inquiry of a case and the DNS that an evaluation passes to for long time became the time-out by the SPF implementation, I can stop the evaluation as a temporary error (TempError). You must return a lasting error (PermError) when SPF needs an inquiry more than 10 directly or indirectly. "redirect= is also" counted for this processing restrictions.
"v=spf1 a -all" which is standard SPF declaration needs three times of DNS inquiries like (1)TXT record, (2) SPF record, (3)A or AAAA record. Because the number of this last DNS inquiries is a thing added up towards limit (10) by the first mechanism, and "all" does not need a DNS inquiry in this example, the first mechanism is the last.
Attention
When domains of the sender address (envelope sender displayed by Return-Path) are usually fair, I only confirm the SPF. The domain (e.g., virtual hosting) to share a transmission email server can give its separate domain names each. I do not confirm the SPF to function in network layer whether a predetermined E-mail really arrives from a person named a sender.
Refusal by the inspection failure
The declaration to fail inspection can become the effective thing, but is dangerous means. Therefore SoftFail may be declared (made for a limited study time) in substitution for Fail to evade danger. However, delivery email server refuses the E-mail which became Fail, and, as for the E-mail which became SoftFail, in SoftFail, it can be the thing which is more dangerous to the above than Fail by accepting you as a promising thing of the unwanted e-mail.
The behavior when I refused a transfer email is clear. In that case, the email server of the origin of transfer sends an error email to the e-mail address provided in Return-Path. The address that failed in explanation and the delivery of the SMTP error (the forwarding address) is included in a general error email (response). I imitate "551 User not local; please try <forwarding address address>" which is a normal SMTP error code, and the original sender detours around the email server of the transfer cause and can retransmit a direct E-mail to a forwarding address address.
However, the E-mail of SoftFail which I received as the thing which there is possibility of the unwanted e-mail in may be deleted by the final addressee. The user with the experience of the transfer setting not to consider SPF may easily delete it without confirming the thing which there is possibility of the unwanted e-mail in and a done E-mail carefully.
The same logic suggests that the delivery email server should catch the SPF suggestion to refuse a true inspection failure email. 迷惑メールの可能性がある物として検証不合格メールを受け入れることは、検証不合格メールを簡単に拒否する事よりさらに危険となり得る。 送信者ドメインにおいて検証に不合格となる宣言がされていて、それが何を意味するか知った上で宣言されていると期待できる場合は、検証不合格となったとしても、それは明らかにSPFを考慮しない転送設定により転送された物ではない。
