Tom qab 14 lub hlis ntawm txoj kev loj hlob, ib ceg ruaj khov tshiab ntawm Postfix mail server - 3.8.0 - tau tso tawm. Tib lub sijhawm, nws tshaj tawm qhov kawg ntawm kev txhawb nqa rau Postfix 3.4 ceg, tso tawm thaum pib ntawm 2019. Postfix yog ib qho ntawm cov haujlwm tsis tshua muaj kev sib txuas nrog kev ruaj ntseg, kev ntseeg siab thiab kev ua tau zoo tib lub sijhawm, uas tau ua tiav ua tsaug rau kev xav txog kev tsim vaj tsev zoo thiab txoj cai nruj nruj rau kev tsim qauv thiab thaj chaw kuaj xyuas. Txoj haujlwm code raug faib raws li EPL 2.0 (Eclipse Public License) thiab IPL 1.0 (IBM Public License).
Raws li kev tshawb fawb Lub Ib Hlis Ntuj txog li 400 txhiab tus xa ntawv, Postfix yog siv rau 33.18% (ib xyoo dhau los 34.08%) ntawm cov xa ntawv xa ntawv, feem ntawm Exim yog 60.27% (58.95%), Sendmail - 3.62% (3.58 %), MailEnable - 1.86% (1.99%), MDaemon - 0.39% (0.52%), Microsoft Exchange - 0.19% (0.26%), OpenSMTPD - 0.06% (0.06%).
Main innovations:
- SMTP / LMTP tus neeg siv khoom muaj peev xwm txheeb xyuas DNS SRV cov ntaub ntawv los txiav txim siab tus tswv tsev thiab chaw nres nkoj ntawm cov neeg xa ntawv xa ntawv uas yuav siv los hloov cov lus. Piv txwv li, yog tias koj teev "use_srv_lookup = xa" thiab "relayhost = example.com:submission" hauv qhov chaw, SMTP tus neeg siv yuav thov SRV tus tswv tsev cov ntaub ntawv _submission._tcp.example.com los txiav txim tus tswv tsev thiab chaw nres nkoj ntawm xa ntawv lub rooj vag. Cov lus pom zoo tuaj yeem siv rau hauv kev tsim kho vaj tse uas cov kev pabcuam nrog cov chaw nres nkoj sib txuas sib txuas tau siv los xa email.
- Daim ntawv teev cov algorithms siv los ntawm lub neej ntawd hauv TLS qhov chaw tsis suav nrog SEED, IDEA, 3DES, RC2, RC4 thiab RC5 ciphers, MD5 hash thiab DH thiab ECDH qhov tseem ceeb pauv algorithms, uas yog cais raws li siv tsis tau lossis tsis siv. Thaum qhia meej hom "export" thiab "qis" cipher hom hauv qhov chaw, hom "nruab nrab" tam sim no tau teeb tsa, txij li kev txhawb nqa rau hom "export" thiab "low" tau raug txiav tawm hauv OpenSSL 1.1.1.
- Ntxiv qhov chaw tshiab "tls_ffdhe_auto_groups" los pab rau FFDHE (Finite-Field Diffie-Hellman Ephemeral) pawg kev sib tham raws tu qauv hauv TLS 1.3 thaum tsim nrog OpenSSL 3.0.
- Txhawm rau tiv thaiv kev tawm tsam txhawm rau txhawm rau txhawm rau muaj kev nco, suav nrog kev txheeb cais "smtpd_client_*_rate" thiab "smtpd_client_*_count" yog muab rau hauv cov ntsiab lus ntawm cov blocks network, qhov luaj li cas tau teev tseg los ntawm cov lus qhia "smtpd_client_ipv4_prefix_length" thiab "smtpd_6_client" los ntawm default /32 thiab /84)
- Ntxiv kev tiv thaiv kev tawm tsam uas siv TLS kev sib txuas lus thov rov hais dua nyob rau hauv ib qho kev sib txuas SMTP uas twb tau tsim los tsim CPU tsis tsim nyog.
- Cov lus txib postconf muab lus ceeb toom rau cov lus teev tseg tam sim ntawd tom qab qhov ntsuas qhov tseem ceeb hauv Postfix teeb tsa cov ntaub ntawv.
- Nws muaj peev xwm los teeb tsa tus neeg siv khoom encoding rau PostgreSQL los ntawm kev qhia qhov "encoding" tus cwj pwm hauv cov ntaub ntawv teeb tsa (los ntawm lub neej ntawd, tam sim no tus nqi tau teeb tsa rau "UTF8", thiab yav dhau los "LATIN1" encoding tau siv).
- Nyob rau hauv postfix thiab postlog commands, log output rau stderr yog tam sim no tsim txawm hais tias qhov kev twb kev txuas ntawm stderr kwj mus rau lub davhlau ya nyob twg.
- Nyob rau hauv lub hauv paus ntoo, cov ntaub ntawv "global/mkmap*.[hc]" tau tsiv mus rau "util" directory, tsuas yog cov ntaub ntawv "global/mkmap_proxy.*" tau tso rau hauv phau ntawv tseem ceeb.
