Tom qab ib xyoos ntawm kev loj hlob tso tawm ib ceg ruaj khov tshiab ntawm tus xa ntawv . Nyob rau tib lub sijhawm, ceg tau txiav tawm , tso tawm thaum ntxov 2016. Postfix yog ib qho ntawm cov haujlwm tsis tshua muaj ua ke nrog kev ruaj ntseg siab, kev ntseeg siab thiab kev ua tau zoo tib lub sijhawm, uas tau ua tiav ua tsaug rau kev xav. thiab ib txoj cai nruj nruj rau cov qauv tsim thiab thaj chaw kuaj xyuas. Txoj haujlwm code yog muab faib raws li EPL 2.0 (Eclipse Public License) thiab IPL 1.0 (IBM Public License).
Raws li lub Peb Hlis hais txog ib lab xa ntawv, Postfix yog siv rau ntawm 34.29% (34.42%) ntawm cov xa ntawv xa ntawv,
Exim qhov sib koom yog 57.77% (ib xyoos dhau los 56.91%), Sendmail - 3.83% (4.16%), MailEnable - 2.12% (2.18%), MDaemon - 0.77% (0.91%), Microsoft Exchange - 0.47% (0.61%).
ntsiab :
- Ntxiv load balancer raws tu qauv txhawb nqa nrog kev tso npe thov ntawm TCP dhau IPv4 thiab IPv6 lossis tsis muaj kev sib txuas ua ke (kom xa cov ntawv thov lub plawv dhia kom paub meej tias kev ua haujlwm ib txwm muaj).
- Ntxiv qhov muaj peev xwm los yuam cov lus kom raug teeb tsa rau stale (undeliverable) raws li txoj cai kom rov qab mus rau tus xa. Cov xwm txheej tau khaws cia rau hauv cov ntawv xa khoom xa tuaj raws li tus cwj pwm tshwj xeeb, nyob rau hauv lub xub ntiag ntawm qhov kev sim xa khoom yuav ua rau cov lus xa rov qab mus rau tus neeg xa ntawv, yam tsis tau muab tso rau hauv cov kab tuav. Txhawm rau teeb tsa tus cwj pwm tsis zoo, cov chij "-e" thiab "-f" tau ntxiv rau cov lus txib postsuper; qhov txawv nrog tus chij "-f" yog tias cov lus raug xa rov qab tam sim ntawd rau tus xa thaum nws nyob hauv queue tos yuav resent. Cov zis ntawm mailq thiab postqueue commands yuam cov lus stale yuav tsum tau cim nrog "#" tom qab cov ntaub ntawv npe.
- Ntxiv kev txhawb nqa rau kev teev npe ntau tus tswv rau SMTP thiab LMTP cov neeg siv khoom los hloov cov lus rau lwm tus neeg rau zaub mov (tom ntej-hop). Cov npe teev npe yuav raug sim xa cov lus hauv qhov kev txiav txim lawv tshwm sim (yog tias thawj qhov tsis muaj, xa khoom yuav raug sim mus rau qhov thib ob, thiab lwm yam). Cov npe tshwj xeeb yog siv rau relayhost, transport_maps, default_transport thiab sender_dependent_default_transport_maps cov lus qhia.
/etc/postfix/main.cf:
relayhost = foo.example, bar.example
default_transport = smtp:foo.example, bar.example - Hloov tus cwj pwm log. Cov chaw nyob hauv "los ntawm =" thiab "rau =" tam sim no tau txais kev cawmdim siv cov lus hais - yog tias thaj chaw hauv cheeb tsam ntawm qhov chaw nyob muaj qhov chaw lossis cov cim tshwj xeeb, ib feem ntawm qhov chaw nyob yuav raug muab kaw rau hauv cov lus hauv lub cav. Txhawm rau rov qab tus cwj pwm qub, ntxiv "info_log_address_format = internal" rau cov chaw.
Yog: los ntawm = [email tiv thaiv]>
Tam sim no: los ntawm =<βnpe nrog qhov chawβ@example.com>. - Xyuas kom normalization ntawm IP chaw nyob tau los ntawm XCLIENT thiab XFORWARD headers los yog los ntawm HaProxy raws tu qauv. Qhov kev hloov pauv tuaj yeem ua txhaum kev sib raug zoo ntawm qib log thiab IPv6 subnet mappings hauv daim ntawv qhia check_client_access.
- Txhawm rau txhim kho qhov yooj yim ntawm kev sib cuam tshuam nrog Dovecot, SMTP + LMTP tus neeg xa khoom xa tuaj muab cov ntawv txuas ntawm Kev Xa-Rau, X-Original-Rau thiab Rov Qab-Path headers siv "chij = DORX" chij hauv master.cf, zoo ib yam li cov yeeb nkab. thiab cov neeg xa khoom hauv zos.
- Cov txheej txheem rau kev txheeb xyuas daim ntawv pov thawj uas tau teev tseg hauv cov ntawv check_ccert_access yog txhais. Ua ntej, ib qho snapshot ntawm daim ntawv pov thawj tus neeg siv khoom raug kuaj xyuas, thiab tom qab ntawd tus neeg siv khoom tus yuam sij pej xeem (tus cwj pwm zoo li thaum qhia "search_order = cert_fingerprint, pubkey_fingerprint").
