[Postfixbuch-users] Mails mit Anhang gehen schlecht durch

[Michael Mertel]

Hi,

ich habe seit einigen Tagen das Problem, das Mails mit Anhang von kundenserver.de nur noch sehr verzögert durchgehen, teilweise mit 2+ Tagen Verspätung. Grund für die Verspätung ist wohl das die Verbindung abbricht.

Jul 15 09:52:18 srv-1 postfix/smtpd[2125]: timeout after DATA from moutng.kundenserver.de[212.227.126.186]

Vom Connect bis zum Timeout dauert es ziemlich genau 5 Minuten, was dem smtpd_timeout entsprechen würde, aber wenn Daten fließen sollte der sich doch wohl immer wieder erneuern?

Hättet ihr da mal einen heißen Tip für mich?


Achja, postconf -n :)
