khululiwe, kunjalo umphathi weposi (Ummeli wezoThutho lweMeyile, uhlala eyi-MTA) iphuhliswe ukuba isetyenziswe kwiinkqubo ezininzi ze-Unix, kubandakanya iGNU / Linux.
Este Unobhetyebhetye olukhulu kwiindlela imiyalezo engayilandela ngokwemvelaphi yazo kunye ne-por ukwazisa ukusebenza kolawulo logaxekile, uluhlu lweebhloko ezisekwe kwi-DNS (I-DNSBL), ii-virus, ulawulo lwe-relay, abasebenzisi kunye nemimandla ebonakalayo nabanye, Ezicwangciswe ngakumbi okanye zigcinwa ngokulula kwaye zigcinwa.
Iprojekthi inamaxwebhu afanelekileyo, imizekelo "yokwenza" imisebenzi ethile. Exim isasazwa simahla phantsi kwelayisenisi yeGNU GPL.
Malunga nohlobo olutsha lwe-Exim 4.94
Le nguqulo intsha ye-Exim 4.94 ifika emva kweenyanga ezi-6 zophuhliso, apho izilungiso eziqokelelweyo zazisiwe, iimpawu ezintsha zongezwa, kodwa ngaphezulu kwazo zonke ezinye iinguqu ezibalulekileyo ezenziwe ezinokubangela iingxaki zokuhambelana neenguqulelo zangaphambili.
Ngokukodwa ezinye iindlela zothutho ziyekile ukusebenza nedatha eluhlaza xa umisela indawo yokuhambisa.
Kwicala leendaba zenguqulo entsha, ifayile ye- Inkxaso yokulinga eyakhelweyo kwindlela ye-SRS (Inkqubo yomthumeli yokubhala kwakhona), ethi Ivumela ukuphinda kubhalwe idilesi yomthumeli xa ugqithisa ngaphandle kokophula i-SPF (Isakhelo somgaqo-nkqubo weSender) kwaye uqinisekise ukuba idatha yomthumeli igcinwe kwiserver ukuthumela imiyalezo kwimeko yosilelo lokuhambisa.
Umongo wendlela kukuba xa uxhulumaniso lusekiwe, ulwazi malunga nesazisi kunye nomthumeli wokuqala luyahanjiswa.
Ngelixa lecala xa usebenzisa I-OpenSSL, inkxaso yepini yesitayile iye yongezwa kubaqinisekisi (ngaphambili yayihambelana kuphela neGnuTLS).
Inkqubo ye- icala lokuxhasa uqinisekiso lwenkxaso ye-gsasl, Evavanywa kuphela kumqhubi wombhalo ocacileyo. Ukusebenza kwe-SCRAM-SHA-256 kunye ne-SCRAM-SHA-256-PLUS iindlela zinokwenzeka kuphela nge-gsasl.
Ukongeza kwinto yokuba i kwicala leseva gsasl isinisiqinisekiso senkxaso yamagama agqithisiweyo afihliweyo, eyenye indlela eyahlukileyo kwimo ebifumaneke ngaphambili yokubhaliweyo.
Kwelinye icala, isibhengezo siqaqambisa ukhetho olutsha "sqlite_dbfile" kwibhloko yokumisela ephambili, esetyenziselwa ukumisela isimaphambili somtya wokukhangela.
Kwakhona Inkxaso yovavanyo kwiziseko ze-Intanethi ibonakalisiwe yongezwe kwisilawuli sokuqinisekisa ngeseva ye-Dovecot IMAP (ngaphambili kuphela iziseko ze-unix domain zazixhaswa).
Iibhloko zokukhangela ezikhetha ngesitshixo, ukhetho longezwe ukubuyisela ingxelo ecacisiweyo yesitshixo ukuba kukho ukungqinelana, endaweni yedatha ekhangeloweyo.
Kuko konke ukuphumelela kuluhlu lomdlalo okhethiweyo, izinto eziguquguqukayo $ domain_data kunye $ localpart_data icwangcisiwe (ngaphambili uluhlu lwezinto ezazibandakanyekile kukhetho lwalufakiwe). Uluhlu lwezinto ezisetyenzisiweyo kuthelekiso ngoku zabelwe izinto ezixabisekileyo $ 0, $ 1, njalo njalo.
Olunye utshintsho olwahlukileyo kuhlobo olutsha:
- Kwimigca ye-ACL_kuphela ngoku inokuchazwa njengolayini kwaye ixhase ukhetho lokuqala_pass_route, ngokufanayo -odqs ukhetho lomgca wokuyalela.
- Iinkcazo zoluhlu ezinamagama ngoku zinokufakwa kwindawo ethi "fihla" ukucinezela ukuphuma komxholo xa "-bP" usenziwa.
- Izinto ezintsha eziguquguqukayo $ queue_size kunye $ local_part_ {pre, suf} fix_v zongezwa.
- Kwiibhloko zokukhangela, i-pgsql kunye ne-mysql zongeze ukhetho lokukhankanya igama lomncedisi ngokwahlukileyo kumtya wokukhangela.
- Umnikezeli omtsha wolwandiso «$ {listquote { } { }} ».
- Ukhetho longezwa kumqhubi wolwandiso $ {readsocket {} {} {}} ukubonelela ngokugcina iziphumo.
- Yongeze i-dkim_verify_min_keysizes ukuseta kuluhlu lobuncinci obuvumelekileyo bezitshixo zoluntu.
- Ukuxelwa kwe "bounce_message_file" kunye ne "warn_message_file" yeeparameter zinikezelwe ngaphambi kokuba zisetyenziswe okokuqala.
- Ukongezwa kokhetho "spf_smtp_comment_template" ukuseta ixabiso lokwahluka "$ spf_smtp_comment".
