After I updated ISPconfig to 3.2.8 and also after the patch to 3.2.8p1 Im having issues with postfix For some receipents Im getting: Mar 28 07:41:06 -- postfix/smtpd[19300]: warning: localhost[127.0.0.1]: SASL PLAIN authentication failed: Mar 28 07:41:06 -- postfix/smtp[19299]: 23D3986: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10025, delay=2.2, delays=0.02/0.06/2.1/0, dsn=4.7.8, status=undeliverable (SASL authentication failed; server 127.0.0.1[127.0.0.1] said: 535 5.7.8 Error: authentication failed: ) Also my server stopped to accept some mails: Mar 24 11:45:11 -- postfix/smtpd[10303]: NOQUEUE: reject: RCPT from mail62.atl261.mcdlv.net[198.2.142.62]: 450 4.1.1 <[email protected]>: Recipient address rejected: unverified address : SASL authentication failed; server 127.0.0.1[127.0.0.1] said: 535 5.7.8 Error: authentication failed: ; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail62.atl261.mcdlv.net> I was able to solve the problem with commenting out the following newly added config from main.cf #address_verify_virtual_transport = smtp:[127.0.0.1]:10025 #address_verify_transport_maps = static:smtp:[127.0.0.1]:10025
It is , and the weird thing, it was only blocking some mails not all. /etc/init.d/amavis status ● amavis.service - LSB: Starts amavisd-new mailfilter Loaded: loaded (/etc/init.d/amavis; generated) Active: active (running) since Mon 2022-03-28 09:05:02 CEST; 47min ago Docs: man:systemd-sysv-generator(8) Process: 513 ExecStart=/etc/init.d/amavis start (code=exited, status=0/SUCCESS) Tasks: 3 (limit: 4698) Memory: 545.8M CGroup: /system.slice/amavis.service ├─1306 /usr/sbin/amavisd-new (master) ├─3158 /usr/sbin/amavisd-new (ch4-avail) └─3159 /usr/sbin/amavisd-new (ch4-avail)

I'd suspect you have a problem with dovecot userdb/passwd lookups, as user verification will be done (past the amavis daemon) via the dovecot lmtp daemon, and sasl authentication is via dovecot auth service. Maybe try restarting dovecot and see if there are any errors in the mail log. You could check that your /etc/dovecot/dovecot.conf looks complete (one other user reported only a partial config file after updating).
I was having the same issue which was solved by restarting the 'amavis' service and commenting the two lines mentionned by aa6tem in 'main.cf'. I then restarted the 'postfix' and 'dovecot' services.
