What a way to start the new year! I got the following message in /var/log/mail.err this morning:
Jan 1 01:34:03 grace postfix/postqueue[1684046]: fatal: Queue report unavailable - mail system is down Naturally, I checked, and both Postfix and Dovecot are running. Can anyone translate this for me? System details: Ubuntu Server 20.04.3, Postfix 3.4.13, Dovecot 2.3.7.2. Further details available on request. Ken
