Hallo Leute,
ich habe seit einigen Tagen Probleme mit Mails von t-online.
mailout**.sul.t-online.com connecten sich, senden EHLO, erhalten von meinem Server Antwort ... und dann ist Stille bis der timeout zuschlägt.
ich habe mal den Verbose-Mode angestellt, aber kann ich nichts erkennen:

Ich habe den Spamhaus-Filter an, greylisting (postgrey) und 2 Firewalls, die nur die Ports 25, 80 und 443 durchlassen. ICMP ist für t-online.com und skype.net erlaubt - sonst blockiert. Die beiden Netze stehen auch in der whitelist von postgrey.
Mittlerweile tauchen öfter vereinzelt weitere Server im Logfile auf, die das selbe Problem zu haben scheinen. Manchmal kommen die Mails dieser Server aber auch durch.
