LinuxQuestions.org - Zimbra server and perl problem

I've installed Zimbra (zcs-4.0.3) on a Debian unstable box.

The box specs are as follows:

Penguin Relion 120 w/dual PIII/933 CPUs
2GB RAM
Dual 36GB SCSI hard drives, RAID 1

No mail is being delivered, everything is being deferred. The logs show errors similar to:

Code:

I have asked on the Zimbra forums, but gotten no answers, so I am hoping someone here can help. My own research shows that it appears to be amavisd. One post stated that the older versions of amavisd (2.3.3) did not play nicely with Net::Server > 0.91. Zimbra 4.0.3 ships with amavisd 2.4.1, but I downgraded to Net::Server to 0.87 from Debian/stable, to no avail. file is in the path (/usr/bin), and I have made sure both the Server.pm in /usr/share/perl5/Net and /opt/zimbra/zimbramon/lib/Net were 0.87, but still I get these errors and no mail sent or delivered. Has anyone found anything else which might cause these errors?

Thanks,
