[Postfixbuch-users] Timeouts beim senden

Hallo zusammen,

ich habe mit folgender Konstellation ein Problem: Auf einem Linux-Server mit
permanenter Anbindung an das Internet läuft Postfix, dahinter befindet sich 
ein HPUX mit sendmail.

Dieses sendmail fabriziert nun bei einigen E-Mails Timeouts. Dabei scheint es
sich eher um größere E-Mails zu handeln, aber nicht ausschliesslich.

In meiner postfix-Log sieht das so aus:
ug  6 09:26:31 gateway postfix/smtpd[4062]: connect from unix1.absender.de[194.175.86.2]
Aug  6 09:26:31 gateway postfix/smtpd[4062]: 136A0AB5A: client=unix1.absender.de[194.175.86.2]
Aug  6 09:34:43 gateway postfix/smtpd[4062]: timeout after DATA from unix1.absender.de[194.175.86.2]

Scheint erst mal ein sendmail-Problem zu sein. Dort sieht das so aus:
Aug  5 14:29:41 unix1 sendmail[13261]: h75CTRL6013261: from=<userxy at absender.com>, size=517889, class=0, nrcpts=1, msgid=<000001c35b4d$ecb59b40$78
56afc2 at PC20>, proto=ESMTP, daemon=MTA, relay=pc20.absender.de [194.175.86.120]
Aug  5 14:36:09 unix1 sendmail[13325]: h75CTRL6013261: to=<info at irgendwo.de>, delay=00:06:40, xdelay=00:06:27, mailer=relay, pri=120598, rela
y=gateway.absender.de. [194.175.86.60], dsn=4.0.0, stat=I/O error
Aug  5 15:07:40 unix1 sendmail[20607]: h75CTRL6013261: SYSERR(root): timeout writing message to gateway.absender.de.: Connection timed out with gateway.centa-
star.de.
Aug  5 15:07:40 unix1 sendmail[20607]: h75CTRL6013261: to=<info at irgendwo.de>, delay=00:38:11, xdelay=00:15:00, mailer=relay, pri=210598, rela
y=gateway.absender.de. [194.175.86.60], dsn=4.0.0, stat=Deferred

Nun hab ich mir gedacht, was soll, sollen die eben direkt den Linux-Postfix
als SMTP Server eintragen und direkt verschicken. Nur da scheint es auch
immer wieder dieses Problem zu geben. Ich fürchte daher, dass das Problem
bei Postfix zu suchen ist. 

Bei der Suche im Netz habe ich jedoch auch gefunden, dass die sendmail-
Meldung "dsn=4.0.0, stat=I/O error" auf ein DNS Problem hinweist. Nur
nicht auf welches.

Daher habe ich mal ein ausführliches Protokoll beim postfix aktiviert
(Level 9) und den unten angefügten Log bekommen. Ich hoffe ich habe 
ihn angemessen gekürzt.

Was kann ich tun um das Problem weiter einzugrenzen?

Danke + Gruß,
Jan
