After updating to 3.2.1 with service reconfiguration, my private mail setup dovecot/postfix (perfect server setup Debian 10) stopped working. My user cannot be authenticated anymore from the mail client and webmail. Incoming mails seem to work, log entries indicate they get sorted into the INBOX. Maybe related to https://www.howtoforge.com/community/threads/smtp-server-offline.85705/ where discussion started /var/log/mail.err: Code: Nov 24 19:42:35 xx dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF Nov 24 19:42:35 xx dovecot: auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused Nov 24 19:42:35 xx dovecot: auth: Error: net_connect_unix(/var/run/dovecot/stats-writer) failed: Connection refused /etc/postfix/main.cf Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

Please do not post the same thing in two threads: https://www.howtoforge.com/community/threads/smtp-server-offline.85705/
Thx for cleaning up, that's why I started this with the same information. So we close this and continue in https://www.howtoforge.com/community/threads/postfix-offline-sasl-error.85707/
