Subject: Bad SMTP prompt at the host, smtp closing connection during sending
Date: Wed, 24 Jun 2009 07:15:35 -0700
To: <CGatePro>

We have problems sending emails to some providers (among them xs4all.nl). It looks like CommunigatePro is closing connection while handshaking. We are not blacklisted. It looks like our ptr's are ok. Looked over a lot of the AUTH settings. Unfortunately, no solution yet. Multihoming could be an issue, however, untill 3 weeks earlier it all seemed ok with same settings and multihoming.

This is the bounce message:

Reporting-MTA: dns; researchsoftware.nl

SMTP module(domain @192.168.20.154:xs4all.nl) reports:
 mx2.xs4all.nl: Bad SMTP prompt at the host

 


We have a firewall/router and 192.168.20.154 is our mail server IP (natted, WAN IP is 87.249.111.154). I have listed here two log sections from our mail server:
