Hallo zusammen,
seit einigen Tagen bekomme ich regelmäßig immer wieder diese Nachricht per Mail vom Server bzw. Watchdog:
"The Dovecot IMAP and POP3 server service on host xx.xxxx.xx is down.
The problem was discovered on Dec 10, 2021 08:49 PM."
Gerade habe ich mal ins Logfile geschaut und dies hier zu dieser Zeit gefunden:
(Ich weiß nicht, ob das alles dazugehört, aber es passt zum Zeitraum als die Mail von Watchdog kam.)
Zum System:
Debian 9.13
Plesk Obsidian Version 18.0.40 Update #1
Was kann hier das Problem sein? Danke schon mal!
