[Postfixbuch-users] langsamer Verbindungsaufbau

[Thomas]

Hallo.

Ich habe ein Problem mit postfix 2.0.18 (auf FC2). Es dauert ca. bis zu 30
Sekunden bis ich die erste 220 Status Meldung erhalte.
220 mx01.domain.com ESMTP Postfix
Danach läuft aber alles einwandfrei. An der DNS Konfiguration liegt es
nicht, die habe ich bereits überprüft. Ich habe auch schon alle checks
deaktiviert und selbst das bringt keine Veränderung
Ich kann mir echt nicht erklären warum es so lange dauert und bin
mittlerweile recht ratlos. Ich bin für jeden Tip sehr dankbar.
