[ERLEDIGT] fail2ban und iptables

[vbbaby]

Moin....
manchmal kann man auf meinem Server keine Emails mehr senden und empfangen....das heißt die Mails werden zwar vom Server empfangen, allerdings nicht an die User ausgeteilt.....
Nach einigen Nachforschungen habe ich nun folgendes im Logfile von fail2ban gefunden:

Wahrscheinlich wurden also seit 14:42 keine Mails mehr verteilt und man konnte auch keine versenden, das würde zumindest hinkommen.....

Hat jemand eine Ahnung wie ich das Problem hier lösen kann ?
Danke schon mal für jeglichen Tipp....
