[Kroupware] Postfix problems

[Stephan Buys]

Hello all,

We are having problems sending mail internationally and keep on getting errors like the following:

Nov 05 07:50:55 mail <info> postfix/smtp[2330]: 289F12B21EE: to=<REMOVED>, relay=REMOVED, delay=78013, status=deferred (host REMOVED said: 451 Timeout waiting for end of DATA. Be sure your client is not sending bare linefeeds. (in reply to end of DATA command))
Nov 05 07:51:02 mail <info> postfix/smtp[2359]: 7A6062B22E1: to=<REMOVED>, relay=REMOVED, delay=430758, status=deferred (host REMOVED said: 421 Error: timeout exceeded (in reply to end of DATA command))
Nov 05 07:51:03 mail <info> postfix/smtp[4248]: connect to REMOVED: Operation timed out (port 25)

Any ideas? Could this be a transparent proxy/firewall at the ISP problem?

Anyone have similar problems yet?

This box uses the latest and greatest Kolab packages running on FreeBSD.

Regards,
