i am trying to run a selfhosted mailserver using postfix and dovecot. firstly i configured only postfix without dovecot and that worked fine but i wanted to use a mail client so i installed dovecot to configure it. Now when i try to send and receive mail i get an error in postfix about SASL. First i get a warning aboutr connecting to private/auth failed:

Dec 14 12:50:56 debian postfix/smtpd[33959]: warning: SASL: Connect to private/auth failed: Connection refused 

after that i get a fatal error:

Dec 14 12:50:56 debian postfix/smtpd[33959]: fatal: no SASL authentication mechanisms 

I tried reinstalling and re configuring everything but that also sadly did not help. i tried following some online tutorials for setting this up: tutorial

If anyone has some advice it would be really appreciated.

dovecot version: 2.3.13 (89f716dc2) mail_version = 3.5.18 running on debian 11

  • seems it happened due to expiration of ssl for me I renewed ssl and apply it for postfix then issue resolved. Commented Feb 7, 2024 at 1:46
