Zimbalwa izinsuku ezedlule fU-ue umemezele ukukhishwa kwenguqulo entsha ye-Exim 4.95, okuza nochungechunge lwezilungiso eziqoqekayo nezici ezintsha ezingeziwe.
Kulabo abangazi Exim, kufanele wazi ukuthi lokhu othwala imeyili (Umenzeli Wezokuthutha Ngemeyili, imvamisa i-MTA) ithuthukiswe ukusetshenziswa ezinhlelweni eziningi ze-Unix, kufaka phakathi i-GNU / Linux.
Este inokuguquguquka okukhulu ezindleleni imiyalezo engazilandela ngokuya ngemvelaphi yazo kanye ne-por yethula ukusebenza kokulawulwa kogaxekile, uhlu lwama-block olususelwa ku-DNS (I-DNSBL), amagciwane, ukulawulwa kokudlulisa, abasebenzisi kanye nezizinda ezibonakalayo nabanye, ezilungiselelwe noma zigcinwe kalula kalula.
Iphrojekthi inemibhalo emihle, izibonelo "zokwenza" imisebenzi ethile. I-Exim isatshalaliswa mahhala ngaphansi kwelayisense le-GNU GPL.
Izici ezintsha eziyinhloko ze-Exim 4.95
Kule nguqulo entsha ukusekelwa kwemodi yokulungisa ulayini yemilayezo ye-ramp esheshayo se umemezele ukuthi uzinzile, ini shesha ukuqala kokulethwa kwemiyalezo ngomugqa omkhulu wokuthumela kanye nokuba khona kwenani lemilayezo elihlaba umxhwele elibhekiswe kubasingathi abajwayelekile, ngokwesibonelo, lapho kuthunyelwa umlayezo inani elikhulu lama-imeyili amakhulu kubanikezeli beposi noma ukuthumela ngomenzeli ophakathi wokudlulisa imiyalezo (smarthost).
Futhi ukusekelwa kwe-LMDB kuzinzile compact kuhlanganiswe ukusebenza okuphezulu okugcina idatha ngefomethi yenani lokhiye. Kusekelwa kuphela usesho "lokhiye owodwa" lwemininingwane engaphandle kwebhokisi (ukubhala kusuka ku-Exim kuya ku-LMDB akusetshenziswanga).
Olunye ushintsho olugqamile yilolo ukuqaliswa kokusebenza kwendlela ye-SRS kwaqiniswa (Isikimu Sokubhala Sender): "I-SRS_NATIVE", engadingi ukuncika kwangaphandle (ukusetshenziswa kwangaphambilini kokuhlola kwakudinga ukuthi umtapo wolwazi we-libsrs_alt ufakwe). I-SRS ivumela ikheli lomthumeli ukuthi libhalwe kabusha ekuthumeleni ngaphandle kokuphula i-SPF nokuqinisekisa ukuthi idatha yomthumeli igcinelwa iseva ukuthumela imilayezo uma kwenzeka ukwehluleka kokulethwa.
Ngaphezu kwalokho, singakuthola lokho ungeze ukusekelwa kwe- "file = » emibuzweni yokusesha ku-SQLite, ekuvumela ukuthi ucacise ifayela ledatha lokwenza okuthile ngaphandle kokucacisa iziqalo zomugqa ngomyalo we-SQL.
Emibuzweni yokusesha ye-Lsearch, ukungezwa kufakwe inketho ye- "ret = full" ukubuyisa lonke ibhulokhi ledatha elihambisana nokhiye, hhayi nje umugqa wokuqala.
Ukusungula ukuxhumeka kwe-TLS kuyasheshiswa ngokulayisha ngokuningiliziwe nemininingwane yokulondolozwa kwesikhashana (ngokwesibonelo, izitifiketi) kunokuyilanda ngaphambi kokucubungula ukuxhumana ngakunye.
Kwezinye izinguquko okugqamile:
- Kungezwe inketho ye- "message_linelength_limit" ukusetha umkhawulo enanini labalingiswa kulayini.
- Ikhono lokudlula inqolobane lapho wenza izicelo zosesho linikiwe.
- Ngokuthuthwa kokunamathiselwe, ukuhlolwa kwesabelo kuyasetshenziswa lapho kutholwa umyalezo (iseshini ye-SMTP).
- Kungezwe ipharamitha ye- "proxy_protocol_timeout" ukusetha ukuphela kwesikhathi se-proxy protocol.
- Kungezwe ipharamitha "smtp_backlog_monitor" ukunika amandla ukungena kwemininingwane ngosayizi we-backlog.
- Ipharamitha ye- "hosts_require_helo" ingeziwe ukuvimbela ukudluliswa komyalo we-MAIL uma umyalo we-HELO noma we-EHLO ungazange uthunyelwe ngaphambilini.
- Kungezwe ipharamitha ye- "allow_insecure_tainted_data", lapho kucaciswa ukuphepha ngokungavikeleki kwezinhlamvu ezikhethekile kudatha kuzoholela ekuxwayisweni esikhundleni sephutha.
- Ukuxhaswa kwepulatifomu kwe-MacOS okuyekisiwe (amafayela wokwakha ahlelwa kabusha njengasekelwa).
- Kuqiniswe inketho ye-TLS_RESUME, enikeza amandla okuqhubeka nokuxhumeka kwe-TLS okwaphazamiseka ngaphambilini.
Landa i-Exim 4.95
Ukuthola le nguqulo entsha ye-Exim 4.95 kufanele uye kuwebhusayithi yayo esemthethweni lapho esigabeni sayo sokulanda ungathola izixhumanisi ezihambelana nale nguqulo entsha.
