Kana iyo modhi ikagoneswa uchishandisa iyo "queue_fast_ramp" sarudzo uye maviri-nhanho mutsara kugadzirisa ("-qq") inoona kuvepo kwechikamu chikuru chemeseji inonyorerwa kune chaiyo mail server, ipapo kuendesa kune iyo host inotanga pakarepo.
- Imwe nzira yekumisikidzwa kweSRS (Sender Rewriting Scheme) yakagadziriswa - "SRS_NATIVE", iyo isingade kutsamira kwekunze (yechiyedzo yekare kuita inodiwa kuisa libsrs_alt raibhurari). SRS inokutendera kuti unyorezve kero yeanotumira panguva yekutumira pasina kutyora SPF (Sender Policy Framework) macheki uye nekuona kuti data rekutumira rinochengeterwa sevha kutumira mameseji kana ikatadza kuburitsa. Chinokosha cheiyo nzira ndechekuti kana kubatanidza kwatangwa, ruzivo rwekuzivikanwa nemutumiri wepakutanga runofambiswa, semuenzaniso, pakunyora patsva.

- Sarudzo yeTLS_RESUME yakagadziriswa, ichipa kugona kutangisa kubatanidza kwakambovhiringwa TLS.
- Tsigiro yeiyo yepamusoro-inoshanda compact yakamisikidzwa LMDB DBMS, iyo inochengeta data mukiyi-kukosha fomati, yakagadzikana. Chete chekutarisa masampula kubva akagadzirira-akagadzirwa dhatabhesi uchishandisa kiyi imwe chete anotsigirwa (kunyora kubva kuExim kuenda kuLMDB hakuna kuitwa). Semuenzaniso, kuti utarise nzvimbo yeanotumira mumitemo, unogona kushandisa mubvunzo wakaita sekuti "${lookup{$sender_address_domain}lmdb{/var/lib/spamdb/stopdomains.mdb}}".
- Yakawedzerwa sarudzo "message_linelength_limit" kuseta muganhu pahuwandu hwemavara pamutsetse.
- Iko kugona kufuratira cache kana kuita zvikumbiro zvekutsvaga kwakapihwa.
- Pakufambisa kweappendfile, kutariswa kwekota kwaitwa uchigamuchira meseji (SMTP chikamu).
- Yakawedzera rutsigiro rwe "faira =" sarudzo muSQLite yekutarisa mibvunzo ", iyo inokutendera kuti utaure dhatabhesi faira kune chaiyo oparesheni pasina kudoma prefixes mumutsara nemurairo weSQL.
- Tsvagurudzo yekutarisa mibvunzo ikozvino inotsigira iyo "ret = yakazara" sarudzo yekudzosera iyo data block inoenderana nekiyi, kwete yekutanga mutsara.
- Kumisikidza TLS zvinongedzo kunomhanyisa nekutora uye caching ruzivo (senge zvitupa) pane kudhawunirodha usati wagadzirisa imwe neimwe yekubatanidza.
- Yakawedzera parameter "proxy_protocol_timeout" kugadzirisa nguva yekupera kweProxy protocol.
- Yakawedzera parameter "smtp_backlog_monitor" kugonesa kurekodha kweruzivo nezve saizi yemutsara wekumirirwa kwekubatanidza (backlog) mulog.
- Yakawedzera "hosts_require_helo" parameter, iyo inorambidza kutumira MAIL murairo kana HELO kana EHLO murairo usina kumbotumirwa.
- Yakawedzera iyo "allow_insecure_tainted_data" parameter, kana yatsanangurwa, kutiza zvisina kuchengetedzeka kwemavara akakosha mudata kunoguma yambiro pane kukanganisa.
