[Postfixbuch-users] Connection timed out

[lists at marcus-schneider.com]

Guten Tag,

ich habe das Problem das ich 80% der ausgehenden Mails nicht versendet bekomme.
T-online und GMX, gehen überhaupt nicht. Einige andere Domains funktionieren immer und wunderbar.

ein telnet mx0.gmx.de 25 wird mit 220 {mx044} GMX Mailservices ESMTP beantwortet.


/var/log/messages
kommt immer:

Dec 31 00:41:50 postfix/smtp[7413]: 32CE2D8C4: to=<alias at gmx.de>, relay=none, delay=30, status=deferred (connect to gm
