freebsd 5.2.1 and exim 4.30 problems

[Andrew Thomson]

I have a bit of strange problem and I'm nearly at my witts end as to
what the cause of the problem is.

Basically I installed a 5.2-RELEASE box and setup my new mailserver.
Then used portupgrade to upgrade any newer versions of software
installed.

I then cvsup'ed to 5.2.1-p4 and now things aren't working too well.

mx2# telnet 0 25
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
220 mx2 ESMTP Exim 4.30 Wed, 31 Mar 2004 14:27:14 +1000
421 mx2 lost input connection
Connection closed by foreign host.

I always get this "connection closed" business before I can send any
commands through!

The problem is that everything works on my desktop, which is a
5.2.1-p4/exim 4.30 combo - thus proving everything should work fine.

The only real differences I guess are in the hardware. The new
mailserver is an SMP box whilst my box is just a standard desktop.

I've tried the following to no avail:

* portupgrade -Rf exim
* make kernel (use GENERIC)
* make kernel (use GENERIC but no smp)
* build/installworld then portupgrade -Rf exim

Everything was working fine but now it's pooched! I'm not sure what to
try next as I had this box all setup ready to be dropped into production
and then this issue arose!

Every other part of the box works fine - ssh, courier-imap, ldap etc
etc.. But not being able to receive mail is quite a fundamental problem!

Any thoughts on what to try next would be appreciated. System rebuild
isn't high on the agenda!! ;)

Thanks,
