[Postfixbuch-users] Postfix Connect Timeout

[Simon Metzger]

Hallo zusammen,

ich habe auf meinem Rootserver Postfix in Verbindung mit Dovecot 
installiert. Für die Userverwaltung wird eine SQL-Datenbank genutzt. 
Dovecot stellt nach außen imap und imaps zur Verfügung. Die Mailabruf 
mit imap/imaps funktioniert einwandfrei. Leider bekomme ich aber wenn 
ich Mails senden möchte (mit Hilfe von Thunderbird), jedes mal einen 
Timeout nach einer gewissen Zeit... also die Connection läuft in ein 
Timeout und die Mail kann nicht gesendet werden.

*Also /var/log/mail.info bringt mit verbose folgende Warnings:*

**Ohne Verbose bringt /var/log/mail.info einfach nur folgendes:
*Apr 27 10:26:11 donald postfix/smtpd[19413]: connect from 
unknown[193.196.7.170]

UNKNOWN from unknown[193.196.7.170]

Ich habe schon einiges probiert... aber komme zu keiner Lösung.
Ich hoffe es hat noch jemand eine Idee.

Viele Grüße
