Moin,
Aufgrund des Heartbleed-Bugs habe ich am Montag eines meiner Systeme
(Ubuntu 12.04.4 LTS) bzw. Pakete dessen geupdated, unter anderem eben
auch Dovecot und Postfix.
Natürlich habe ich auch sämtliche Benutzerpasswörter geändert.
Es besteht nur seit dem Update der Pakete das Problem, dass ich mich
um's verrecken nicht mehr bei Dovecot einloggen kann.
Mails können über Postfix noch versendet werden, wobei ich auch auf dem
25er Port beim Login keinerlei SSL-Zertifikat entgegen geschmissen
bekommen, aber das versenden funktioniert noch.
Das Hauptproblem ist dass nicht mehr einloggen in Dovecot.
Hat hierzu irgendwer eine Idee?
Logs, etc. sind unten.
Vielen Dank schon einmal und Gruß,
Timo
