Iseva ye-imeyile ye-Exim 4.95 ikhululiwe, yongeza izilungiso eziqokelelweyo kunye nokongeza izinto ezintsha. Ngokophando oluzenzekelayo lukaSeptemba olungaphezulu kwesigidi seeseva zeposi, isabelo se-Exim yi-58% (kunyaka ophelileyo 57.59%), i-Postfix isetyenziswe kwi-34.92% (34.70%) yeeseva zeposi, i-Sendmail - 3.52% (3.75% ), I-MailEnable - 2% (2.07) %), MDaemon - 0.57% (0.73%), Microsoft Exchange - 0.32% (0.42%). Utshintsho oluphambili:
- Inkxaso ezinzileyo yemowudi yokujonga umyalezo okhawulezayo uye waziswa, ekuvumela ukuba ukhawulezise ukuqala kokuhanjiswa komyalezo xa ubungakanani bomgca wokuthumela bukhulu kwaye kukho inani elinomtsalane lemiyalezo ethunyelwa kubabuthi abaqhelekileyo, umzekelo, xa uthumela inani elikhulu loonobumba kubanikezeli beposi abakhulu okanye uthumela nge-arhente yokudlulisa umyalezo ophakathi (smarthost). Ukuba imo yenziwe yasebenza kusetyenziswa u-"queue_fast_ramp" ukhetho kunye nezigaba ezibini zokusetyenzwa komgca ("-qq") ibona ubukho benani elikhulu lemiyalezo ethunyelwe kumncedisi weposi othile, emva koko ukuhanjiswa kulo mamkeli kuya kuqalisa ngoko nangoko.
- Olunye ukuphunyezwa kwendlela ye-SRS (iNkqubo yokuBhala ngokutsha yabaThumeli) izinzisiwe - “SRS_NATIVE”, engadingi kuxhomekeka kwangaphandle (ukuphunyezwa kovavanyo oludala olufunekayo ukufakela ithala leencwadi libsrs_alt). I-SRS ikuvumela ukuba ubhale kwakhona idilesi yomthumeli ngexesha lokuthumela ngaphandle kokuphula i-SPF (iSakhelo soMgaqo-nkqubo womThumeli) iitshekhi kunye nokuqinisekisa ukuba idatha yomthumeli igcinwe kumncedisi ukuba athumele imiyalezo xa kukho ukungaphumeleli kokuhanjiswa. Undoqo wendlela kukuba xa uxhulumaniso lusekiwe, ulwazi malunga nesazisi kunye nomthumeli wokuqala luhanjiswa, umzekelo, xa ubhala kwakhona. [imeyile ikhuselwe] phezu [imeyile ikhuselwe] izakuboniswa "[imeyile ikhuselwe]" I-SRS ifanelekile, umzekelo, xa uququzelela umsebenzi woluhlu lokuposa apho umyalezo wokuqala uthunyelwa kwakhona kwabanye abamkeli.
- Ukhetho lwe-TLS_RESUME luzinzisiwe, lubonelela ngesakhono sokuphinda kuqale uqhagamshelo oluphazamisekileyo lwe-TLS.
- Inkxaso ye-high-performance compact embedded LMDB DBMS, egcina idatha kwi-key-value format, iye yazinziswa. Kuphela iisampulu zokujonga ezisuka koovimba beenkcukacha esele benziwe kusetyenziswa isitshixo esinye ezixhaswayo (ukubhala ukusuka kwi-Exim ukuya kwi-LMDB akuphunyezwanga). Umzekelo, ukujonga i-domain yomthumeli kwimigaqo, ungasebenzisa umbuzo onje "${lookup{$sender_address_domain}lmdb{/var/lib/spamdb/stopdomains.mdb}}".
- Ukhetho olongeziweyo "message_linelength_limit" ukuseta umda kwinani labalinganiswa ngomgca ngamnye.
- Ukukwazi ukungahoyi i-cache xa kusenziwa izicelo zokujonga kunikezelwe.
- Kuthutho lwefayile ye-appendfile, uqwalaselo lwekota luye lwaphunyezwa ngelixa ufumana umyalezo (iseshoni yeSMTP).
- Inkxaso eyongeziweyo ye "fayile=" ukhetho kwi-SQLite yemibuzo yokujonga ", ekuvumela ukuba ukhankanye ifayile yesiseko sedatha yomsebenzi othile ngaphandle kokuchaza izimaphambili kumgca nomyalelo weSQL.
- Imibuzo yokukhangela i-Lsearch ngoku ixhasa i-"ret=full" inketho yokubuyisela yonke ibhloko yedatha ehambelana nesitshixo, kungekhona nje umqolo wokuqala.
- Ukuseka imidibaniso ye-TLS kukhawuleziswa ngokulanda kwangaphambili kunye nolwazi lwe-caching (olufana nezatifikethi) endaweni yokuyikhuphela phambi kokuba kuqhutywe uqhagamshelwano ngalunye.
- Kongezwe ipharamitha "proxy_protocol_timeout" ukumisela ixesha lokuphuma kweProxy protocol.
- Ipharamitha eyongeziweyo “smtp_backlog_monitor” ukwenza ushicilelo lolwazi malunga nobungakanani bomgca woqhagamshelo olulindileyo (backlog) kwilog.
- Yongezwe i "hosts_require_helo" iparameter, ethintela ukuthumela umyalelo we-MAIL ukuba umyalelo we-HELO okanye we-EHLO awuzange uthunyelwe ngaphambili.
- Yongeza iparameter "allow_insecure_tainted_tained_data", xa icacisiwe, ukubaleka okungakhuselekanga kwabalinganiswa abakhethekileyo kwidatha kuya kubangela isilumkiso endaweni yempazamo.
- Inkxaso ye-platform ye-macOS iyekile (iifayile ze-assembly zihanjiswe kudidi olungaxhaswanga).
