Hello Len Thanks for all the good suggestions, we�ve tried almost everything. The scariest thing is that the server now works like it used to, and we haven�t done anything?!
We installed some patches for DoS and maybe that worked. Thanks for the quick response.

I doubt if it will help (I've NEVER seen anybody say debug logging helped them find the problem), but you might just try turning on smtp debug logging for a little while. check DNS can you telnet from Imail machine to a remote MX host port 25? somebody screwed up the firewall? do a recursive dir on the mailbox tree, looking for huge .mbx files. anything recently installed? can you virus scan the disk quickly? >We�re running on this particular server Imail 5.09 [I know it�s an old one, >but it has worked like a charm until now...]. It was a great and well-loved, long-serving version for us.
