Idizayini
Imeyili, i-imeyili... “Okwamanje, noma yimuphi umsebenzisi we-novice angazakhela eyakhe ibhokisi leposi lamahhala, avele abhalise kwenye yezingosi ze-inthanethi,” kusho i-Wikipedia. Ngakho-ke ukusebenzisa iseva yakho yemeyili kulokhu kuyaxaka. Noma kunjalo, angizisoli ngenyanga engayichitha kulokhu, ngibala kusukela osukwini engafaka ngalo i-OS kuze kube usuku engathumela ngalo incwadi yami yokuqala kumuntu obhalelwayo ku-inthanethi.
Eqinisweni, abamukeli be-iptv kanye "nekhompuyutha yebhodi elilodwa esekelwe kuphrosesa ye-Baikal-T1," kanye ne-Cubieboard, i-Banana Pi namanye amadivaysi afakwe ama-microprocessors e-ARM angabekwa ezingeni elifanayo "njengama-raspberries." "I-Malinka" ikhethwe njengenketho ekhangiswa kakhulu. Kuthathe isikhathi esingaphezu kwenyanga eyodwa ukuthola okungenani ukusetshenziswa okuwusizo kwale “khompyutha yebhodi eyodwa”. Ekugcineni, nginqume ukwethula iseva yemeyili kuyo, ngisanda kufunda inoveli eqanjiwe yesayensi mayelana neqiniso elibonakalayo.
"Lona umbono omuhle wekusasa leWebhu," kusho iWikipedia. Sekudlule iminyaka engu-20 kusukela ngosuku lokushicilelwa kokuqala. Ikusasa selifikile. Kodwa-ke, akubonakali kukuhle kimi ngaphandle kwababhalisile abayizinkulungwane eziyisikhombisa, ama-ruble ayizinkulungwane eziyishumi "wemali engenayo yanyanga zonke yesayithi lami," njll. Okungase, mhlawumbe, kungiphushele “ezingosini zokuxhumana ezihlukaniselwe izwe” “nenani elincane lokuthandwa kokuthunyelwe kwabo (abasebenzisi abasha - N.M.)”, ukubhalisa isizinda nokuvula iseva yami.
Angikho kahle kwezomthetho. Ngaphandle uma ngithole umlayezo kumakhalekhukhwini wami mayelana nesidingo sokuqinisekisa idatha yomuntu siqu mayelana nokusetshenziswa kwezichibiyelo kumthetho wenhlangano 126-FZ, lona umthetho engiwaziyo.
Futhi-ke kwavela ukuthi le mithetho ifana namakhowe ngemva kwemvula. Ukube ngaqhubeka nokusebenzisa imeyili yamahhala, mhlawumbe ngabe angizange ngazi.
"Futhi ubani mina nawe manje?"
Okokuqala, akekho nje umhleli wenkonzo ye-imeyili emthethweni. Kukhona "umhleli wesevisi yemiyalezo esheshayo," kodwa lokhu kuhluke kancane. Ukwengezwa "kwezidingo zomuntu siqu, zomndeni kanye nezekhaya", yiqiniso, kususa kulo mhleli zonke izibopho ezinikezwe umthetho, kodwa nokho hhayi kumhleli odingekayo.
Ukuba nebhukwana le-Ubuntu Server eduze, kanye nomthetho, ngicabanga ukuthi ngaphezu kwezingxoxo nemiyalezo yabo esheshayo, "yokwamukela, ukudlulisa, ukudiliva kanye (noma) nokucubungula imilayezo ye-elekthronikhi evela kubasebenzisi be-inthanethi," izinsiza ze-imeyili nazo zihloselwe ( okusobala), namaseva wefayela (okungabonakali kangako).
Ukuthuthukiswa
Uma kuqhathaniswa nezinye izindatshana lapha ne-hashtag postfix, indalo yami, vele, ingeyakudala kakhulu. Abukho ukuqinisekiswa komsebenzisi, akukho database, abekho abasebenzisi abangaboshelwe kuma-akhawunti endawo (eyokuqala neyesithathu "zikuseva yemeyili encane"; isizindalwazi sitholakala cishe yonke indawo, njenge-dovecat).
"Ukusetha uhlelo lweposi, ngokubona kwami, kuwumsebenzi onzima kakhulu ekuphathweni kwesistimu," omunye umsebenzisi we-Habra wabhala kahle kakhulu. Ukulandela (ye ), ngiye, nokho, ngashiya izingxenye ezimayelana nesizindalwazi se-alias, amafayela .dlulisela phambili, neziteketiso ezibonakalayo.
Kepha ku-ssl/tls ngithathe imigqa yokumisa eyi-12 kanye nemigqa yemiyalo eyi-9 ye-bash ukudala izitifiketi kuPostfix ezinikezele ku-CommunityHelpWiki (kusizinda esifanayo ) (isebenza kuphela le ssl/tls - umbuzo lowo). I-firewall ku-akhawunti yomuntu siqu yomhlinzeki, nat ku-router (ngiyekile ukumisa i-Mikrotik isikhathi eside ngangokunokwenzeka; ngithumele izincwadi ngokuxhuma iseva ye-imeyili ngqo kukhebula lomhlinzeki we-inthanethi efakwe efulethini), imiyalo mail, mailq, isihlonzi se-postsuper -d, ifayela beliwusizo futhi /var/log/mail.log, ipharamitha always_add_missing_headers, ulwazi mayelana nerekhodi le-ptr, ekugcineni, i-site mail-tester.com (nge-oligophrenic design), okungabhalwanga ngayo “kumeyili ” ezikhuluma ngoHabr, njengokungathi kwakuyindaba nje .
Ngaphambi kokulungisa inani lepharamitha ye-myhostname kufayela /etc/postfix/main.cf
Ngemva kokulungisa inani lepharamitha ye-myhostname kufayela /etc/postfix/main.cf
Incwadi yokuqala evela kwisevisi yokusekelwa kwezobuchwepheshe yomhlinzeki we-inthanethi yangifundisa ukuthi asikho isidingo sokuvula izinhlamvu usebenzisa uhlelo lwe-mail console, ukuze kamuva zikwazi ukuvulwa futhi zifundwe kusetshenziswa iklayenti le-imeyili elijwayelekile. Ngokusobala, lokhu akuyona inkinga "kubaphathi be-novice".
Ngokuphambene nalokho, emazwaneni (kwezinye izindatshana ezine-hashtag ye-postfix) umsebenzisi oyedwa we-Habr ubuza "ukuyixaka kancane, kuthiwani mayelana nokuxhumana kwewebhu ezingxenyeni ezahlukene kanye nokuqinisekiswa okuvela kusizindalwazi", omunye "ngokusobala, yiyona kakhulu okunzima kulabo abangakaze bazame noma yini emnandi kune-radish: ukuphahlazeka kwe-kernel, ukuphepha (selinux/apparmor), amasistimu asabalaliswe kancane...", owesithathu ubhala "nge-iRedmail script". Ulinda nje okulandelayo ukuthi uphakamise ukubhala mayelana ne-IPv6.
Amasevisi e-imeyili awawona amahhashi ayindilinga endaweni engenalutho, ayizingxenye zawo wonke - kusukela ekukhetheni ikhompuyutha negama lesizinda kuya ekusetheni umzila - okungekho bhukwana lokusetha iseva yemeyili elingakwazi ukulifaka (futhi lapho cishe ongeke uze funda ihadiwe - , etholakala kuwebhusayithi esemthethweni ye-Postfix).
I-Mikrotik iyindaba ehluke ngokuphelele.
KULUNGILE sekuphelile Manje. I-imeyili iyekile ukuba isethi yemiyalo ye-console, amafayela okumisa (okuhlanganisa ukusetha i-dns), izingodo, imibhalo, izinombolo ze-hexadecimal esikhundleni sezinhlamvu zesiRashiya (ngokwethebula lezinhlamvu ze-koi8-r) encwadini eyamukelwe futhi ihlale iyi-imeyili ejwayelekile. iklayenti elinephrothokholi yalo imap, pop3, smtp, ama-akhawunti, imilayezo engenayo nethunyelwe.
Ngokuvamile, kubonakala kufana nendlela i-imeyili ebukeka ngayo uma usebenzisa izinsizakalo ze-imeyili zamahhala ezivela ezinkampanini ezinkulu ze-IT.
Nakuba ngaphandle kokuxhumana kwewebhu.
Ukuxhaphaza
Noma kunjalo, akukho ukubalekela ukubuka izingodo!
Ngiyashesha ukujabulisa labo abebelindele ukufunda nge-darknet lapha. Ngoba angikwazi ukukubiza nganoma yini enye ngaphandle kokubonakaliswa kwe-darknet ethile engaqondakali ukuthi ilogi yemeyili yeseva esanda kwakhiwa yagcwaliswa ngayo, okungukuthi, phakathi nezinsuku ezimbalwa (ngemuva kokuxhuma ngokuqondile) ngemilayezo emayelana nemizamo yokuxhuma nge-pop3 ngaphansi kokwehlukile. amagama avela kumakheli ambalwa e-IP ( ekuqaleni ngacabanga ngephutha ukuthi kwakuyiseva ezama ukuthumela izinhlamvu ezimbili ukusuka kulayini, futhi angizange ngicabange ukuthi i-imeyili yami ingathakazelisa omunye umuntu ngokushesha ku-inthanethi).
Le mizamo ayizange ime ngisho nangemva kokuba ngixhume iseva ngomzila. Amalogi anamuhla agcwele ukuxhumana kwe-smtp kusuka ekhelini le-IP elifanayo engilaziyo. Nokho, ngiyazethemba kangangokuthi angenzi lutho ngokumelene nalokhu: Ngethemba ukuthi noma igama lomsebenzisi lokuthola izinhlamvu likhethwe kahle, umhlaseli ngeke akwazi ukuqagela igama eliyimfihlo. Ngiyaqiniseka ukuthi abaningi bazokuthola lokhu kungaphephile, njengokuhlasela kwanamuhla kuncike kuphela kuzilungiselelo zokudluliselwa kwe-SMTP kanye nezilawuli zokufinyelela ku-/etc/postfix/main.cf.
Futhi bayosiphula isivikelo se-imeyili yami kubashayi be-smithereens.
