Exim, kunjalo 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.
Mayelana nenguqulo entsha ye-Exim 4.94
Le nguqulo entsha ye-Exim 4.94 ifika ngemuva kwezinyanga eziyisithupha zentuthuko, lapho kwethulwa khona ukulungiswa okuqoqiwe, kunezelwa izici ezintsha, kepha ngaphezulu kwazo zonke ezinye izinguquko ezibalulekile ezenziwe ezingadala izinkinga zokuhambisana nezinguqulo zangaphambilini.
Ikakhulu ezinye izindlela zokuhamba ziyeke ukusebenza ngemininingwane eluhlaza lapho kunqunywa indawo yokulethwa.
Engxenyeni yezindaba zenguqulo entsha, i- ukwesekwa kokuhlola okwakhelwe ngaphakathi kwendlela ye-SRS (uhlelo lokubhala kabusha lomthumeli), okuyi ivumela ukubhala kabusha kwekheli lomthumeli lapho kudluliswa ngaphandle kokwephula amasheke e-SPF (Uhlaka Lwenqubomgomo Yomthumeli) futhi uqinisekise ukuthi idatha yomthumeli iyagcinwa ukuze iseva ithumele imiyalezo uma kwehluleka ukulethwa.
Ingqikithi yendlela ukuthi lapho kutholakala ukuxhumana, imininingwane ngobunikazi nomthumeli wokuqala iyadluliselwa.
Ngenkathi usebenzisa icala I-OpenSSL, ukuxhaswa kwephini lesiteshi kungeziwe kwabaqinisekisi (phambilini bekusebenzisana kuphela ne-GnuTLS).
I- ukusekelwa kokufakazela ubuqiniso kwe-gsasl kwamakhasimende, evivinywa kuphela ngomshayeli wombhalo ocacile. Ukusebenza kwezindlela ze-SCRAM-SHA-256 ne-SCRAM-SHA-256-PLUS kungenzeka kuphela nge-gsasl.
Ngaphezu kweqiniso lokuthi i- i-server-side gsasl authenticator support for passwords encrypted, okuhlukile kunendlela yombhalo ocacile owawutholakala ngaphambilini.
Ngaphezu kwalokho, isimemezelo siveza inketho entsha "i-sqlite_dbfile" kubhulokhi enkulu yokumisa, ezosetshenziswa ekunqumeni isiqalo sentambo yokusesha.
Futhi Ukusekelwa kokuhlola kwamasokhethi e-Inthanethi kugqanyisiwe ingezwe kusilawuli sokufakazela ubuqiniso ngeseva ye-Dovecot IMAP (phambilini bekuxhaswa kuphela amasokhethi wesizinda se-unix).
Kumabhulokhi okusesha akhethwa ngokhiye, kungezwe inketho yokubuyisa inguqulo esuliwe yokhiye uma kukhona ukufana, esikhundleni sedatha eseshwayo.
Kuzo zonke izinketho zokufaniswa kohlu oluphumelelayo, okuguqukayo kwe- $ domain_data ne- $ localpart_data kusethwe (ngaphambilini izinto zohlu ezazibandakanyekile ekukhethweni zazifakiwe). Futhi, izinto zohlu ezisetshenziswe ekuqhathaniseni manje sezinikezwe okuguqukayo $ 0, $ 1, njalonjalo.
Kwezinye izinguquko ezigqame kusuka enguqulweni entsha:
- Emugqeni we-ACL_kuphela manje sekungachazwa njengomugqa futhi kusekele inketho yokuqala_pass_route, efanayo nenketho yomugqa womyalo we -odqs.
- Izincazelo zohlu olunamagama manje sezingafakwa kuqala ngo- "fihla" ukucindezela okukhiphayo kokuqukethwe lapho umyalo "-bP" ususebenza.
- Okuguqukayo okusha kwe- $ queue_size ne- $ local_part_ {pre, suf} fix_v kungeziwe.
- Kumabhulokhi okusesha, i-pgsql ne-mysql zengeze izinketho zokucacisa igama leseva ngokuhlukile kunentambo yokusesha.
- Isisebenzisi esisha sokwandisa «$ {listquote { } { }} ».
- Inketho ingezwe ku-opharetha wokunweba $ {readsocket {} {} {}} ukunikela ngokulondolozwa kwemiphumela
- Kungezwe ukusethwa kwe-dkim_verify_min_keysizes ukufaka kuhlu osayizi abancane abavunyelwe okhiye bomphakathi.
- Ukudalulwa kwamapharamitha e- "bounce_message_file" ne- "warn_message_file" kunikezwa ngaphambi kokusetshenziswa kwawo kokuqala.
- Kungezwe inketho "spf_smtp_comment_template" ukusetha inani lokuguquguqukayo "$ spf_smtp_comment".
Landa i-Exim 4.94
Ukuthola le nguqulo entsha ye-Exim 4.94 kufanele uye kuwebhusayithi yayo esemthethweni lapho esigabeni sayo sokulanda ungathola izixhumanisi ezihambelana nale nguqulo entsha.
