Ugaxekile uzophela uma kungasenzuzo. Abakwa-Spammers bazobona inzuzo yabo ihlupha uma kungekho muntu othenga kubo (ngoba awuboni ngisho nama-imeyili angenalutho). Lena indlela elula yokulwa nogaxekile, futhi ngokuqinisekile enye yezinto ezinhle kakhulu.
Ukukhalaza Mayelana Negaxekile
Kodwa ungathinta uhlangothi lwezindleko zeshidi lokulinganisela logaxekile. Uma ukhononda kumhlinzeki wesevisi we-Inthanethi ye-spammer (ISP), bazolahlekelwa uxhumano lwabo futhi mhlawumbe kufanele bakhokhe imali (kuye ngokuthi inqubomgomo yokusebenzisa eyamukelekayo ye-ISP).
Njengoba abakwa-spammers bazi futhi besaba imibiko enjalo, bazama ukufihla. Yingakho ukuthola i-ISP efanele akulula ngaso sonke isikhathi. Ngenhlanhla, kunamathuluzi afana ne- SpamCop enza ukubika kogaxekile ngendlela efanele kukheli elilula.
Ukunquma Umthombo Wokugaxekile
U-SpamCop uthola kanjani i-ISP efanele ukukhalaza? Ihlolisisa imigqa yomlayezo wombhalo wogaxekile . Lezi zihloko ziqukethe ulwazi mayelana nendlela i-imeyili ethathe ngayo.
I-SpamCop ilandela indlela kuze kube yilapho i-imeyili ithunyelwe khona. Kusukela kuleli phuzu, futhi uyazi njengekheli le- IP , lingathola i -ISP yogaxekile futhi ithumele umbiko kulo mnyango wokuhlukunyezwa kwe-ISP.
Ake sihlolisise ukuthi lokhu kusebenza kanjani.
Imeyili: Inhloko nomzimba
Yonke imiyalezo ye-imeyli inezingxenye ezimbili, umzimba, kanye nekhanda. Isihloko singacatshangwa njengemvilophu yomyalezo, equkethe ikheli lomthumeli, umamukeli, isihloko kanye nolunye ulwazi. Umzimba uqukethe umbhalo wangempela nezinamathiselo.
Olunye ulwazi lwekhanda ngokuvamile oluboniswa uhlelo lwakho lwe-imeyili luhlanganisa:
- Kusukela: - Igama lomthumeli nekheli le-imeyili .
- Ku: - Igama lomamukeli nekheli le-imeyli.
- Usuku: - Usuku lapho umlayezo uthunyelwe khona.
- Isihloko: - I- subject subject .
Ukufakwa kwekhanda
Ukulethwa kwe-imeyili kwangempela akuxhomeki kunoma iyiphi yalezi zihloko, kulula nje.
Ngokujwayelekile, kusukela ku: umugqa, isibonelo, uzobekwa kukheli lomthumeli. Lokhu kuqinisekisa ukuthi uyazi ukuthi umlayezo uvelaphi futhi ungaphendula kalula.
Abagaxekile bafuna ukuqinisekisa ukuthi awukwazi ukuphendula kalula, futhi ngokuqinisekile abafuni ukuthi wazi ukuthi bangubani. Yingakho efaka amakheli e-imeyili angamanga ku-From: imigqa yemilayezo yabo engafanele.
Yamukelwe: Imigqa
Ngakho kusukela: umzila awunamsebenzi uma sifuna ukunquma umthombo wangempela we-imeyili. Ngenhlanhla, akudingeki sithembele kuso. Izihloko zemiyalezo yonke ye-imeyli iqukethe i-Received: imigqa.
Lezi ngokuvamile aziboniswa izinhlelo ze-imeyili, kodwa zingasiza kakhulu ekulandeleni ugaxekile.
Ukumangalela Kutholiwe: I-Header Lines
Njengencwadi yeposi kuzodabula inombolo yamahhovisi eposi endleleni eya kusuka kumthumeli kuya kumamukeli, umlayezo we-imeyili uphathwa futhi uthunyelwe ngamaseva amaningana weposi.
Cabanga wonke amahhovisi eposi ebeka isitembu esikhethekile encwadini ngayinye. Isitembu singasho ncamashi lapho incwadi yamukelwa khona, lapho ivela nalapho ihanjiswa khona ngeposi. Uma uthola le ncwadi, ungayinquma indlela eqondile eyathathwa yile ncwadi.
Yilokho okwenzekayo nge-imeyili.
Kutholakele: Imigqa yokuThola
Njengoba i- mail server isebenza umlayezo, ineza umugqa okhethekile, otholiwe: umugqa ohlokweni womlayezo. Okutholiwe: umugqa uqukethe, okuthakazelisayo kakhulu,
- igama leseva nekheli le-IP lomshini iseva ithola umlayezo kusuka futhi
- igama leseva yeposi ngokwayo.
Okutholiwe: umugqa uhlale ufakwe phezulu kwezingqikithi zomlayezo. Uma sifuna ukuvuselela uhambo lwe-imeyili kusuka kumthumeli kuya kumamukeli siqala futhi phezulu ekutholeni: umugqa (kungani senza lokhu kuzobonakala emzuzwana) futhi sihambe indlela yethu phansi kuze sifinyelele ekugcineni, lapho i-imeyili ivela.
Kutholakele: Ukufaka Umugqa
Abakwa-Spammers bayazi ukuthi sizosebenzisa le nqubo ncamashi ukuthola ukuthi baphi. Ukuze asikhohlise, bangase bafake i-forged Etholiwe: imigqa ekhomba omunye umuntu othumela umlayezo.
Njengoba zonke izinsizakalo ze-imeyili zizohlala zibeka i-Received yayo: umugqa phezulu, izinhloko ze-spammers 'forged' zingase zibe ngaphansi kwe-Received: line chain. Yingakho siqala ukuhlaziywa kwethu phezulu futhi hhayi nje ukuthola iphuzu lapho i-imeyili ivela kusukela kokutholwa kokuqala: umugqa (ngezansi).
Indlela Yokutshela I-Forged For Received: Line-Header Line
I-forged Itholakele: imigqa efakwe ngabakwa-spammers ukusikhohlisa izobukeka njengezo zonke ezitholiwe: imigqa (ngaphandle uma benza iphutha elisobala, yebo). Ngokwakho, awukwazi ukutshela u-Forged otholiwe: umugqa ovela oqobo.
Lapha lapho isici esisodwa esihlukile seTholakele: imigqa iyadlala. Njengoba siphakamisile ngenhla, wonke amaseva angeke aqaphele ukuthi ubani kodwa kodwa nalapho athola khona umlayezo kusuka (kufomu yekheli le-IP).
Sivele siqhathanise ukuthi isiphakeli esitshela ukuthi sinjani ngalokho iseva elilodwa elifake khona kulolu chungechunge lithi liyilo ngempela. Uma le mibini ingavumelani, i-Received ngaphambilini: umugqa wenziwe.
Kulesi simo, umsuka we-imeyili yilokho iseva ngokushesha ngemva kokutholwa kwe-Forged: umugqa usho ukuthi ubani owathola umlayezo.

Isibonelo Sokuhlaziywa kogaxekile nokulandelwa
Manje njengoba sazi ukusekela okufundiswayo, ake sibone ukuthi ukuhlaziya i-imeyili engadingeki ukukhomba umsuka wayo isebenza empilweni yangempela.
Sithole nje ucezu oluhle logaxekile esingalisebenzisa ekusebenzeni. Nansi imigqa yezinhloko:

Ungatshela ikheli le-IP lapho i-imeyili ivela khona?
Sender and Subject
Okokuqala, sibheke i-forged - Kusuka: umugqa. Ugaxekile ufuna ukubukeka sengathi umyalezo uthunyelwe kusuka ku-Yahoo! I-akhawunti ye-imeyili. Kanye ne-Phendula-Ku: umugqa, lokhu Kusukela: ikheli lihlose ukuqondisa yonke imiyalezo yokuthungatha nokuphendula okuthukuthele ku-Yahoo! engekho. I-akhawunti ye-imeyili.
Okulandelayo, Isihloko: kuyimbumbulu yokufuna izinhlamvu ezingahleliwe. Akucaci kahle futhi ngokucacile yakhelwe ukukhohlisa izihlungi zogaxekile (yonke imiyalezo ithola isethi ehlukile kakhulu yezinhlamvu ezingahleliwe), kodwa futhi ikwazi kahle ukwenza kahle umyalezo naphezu kwalokhu.
Okutholiwe: Imigqa
Okokugcina, okutholiwe: imigqa. Ake siqale ngomdala kunabo bonke, Received: kusuka ku- [235.16.47.37] ngu-38.118.132.100 id; Ilanga, 16 Novemba 2003 13:38:22 -0600 . Awekho amagama abamba kuyo, kodwa amakheli amabili e-IP: 38.118.132.100 athi uthola umlayezo kusuka ku-235.16.47.37. Uma lokhu kuyiqiniso, 235.16.47.37 yilapho i-imeyili ivela khona, futhi singathola ukuthi i-ISP leliphi ikheli le-IP lingelabo, bese uthumela umbiko wokuhlukumeza kubo.
Ake sibone ukuthi okulandelayo (futhi kuleli cala lokugcina) iseva kulesi sikhungo siqinisekisa izimangalo zokuqala ezitholwe: Izimvume zamukelwe: ezingaziwa (HELO 38.118.142.100) (62.105.106.207) nge-mail1.infinology.com nge-SMTP; 16 Nov 2003 19:50:37 -0000 .
Njengoba i-mail1.infinology.com iseva yokugcina ku-chain futhi ngempela "iseva" yethu esazi ukuthi singayethemba. Imukele umlayezo kusuka kumuntu ongaziwa "owaziwa" othi unelungelo le-IP 38.118.132.100 (usebenzisa umyalo we- SMTP HELO ). Kuze kube manje, lokhu kuhambelana nalokho okutholwe ngaphambilini: umugqa uthe.
Manje ake sibone ukuthi isiphakeli sethu seposi sithole umyalezo kusukaphi. Ukuze sithole, sibheka ikheli le-IP kubakaki ngokushesha ngaphambi kwe-mail1.infinology.com . Leli ikheli le-IP uxhumano lwasungulwa kusuka, futhi aluyi-38.118.132.100. Cha, 62.105.106.207 yilapho le ngxenye ye-imeyili engenamagama ithunyelwe khona.
Ngololu lwazi, manje ungakwazi ukubona i-ISP yogaxekile futhi ubike i-imeyili engaceliwe ukuze bakwazi ukukhahlela i-spammer ngaphandle kwenetha.
