Exchange 2003 2007 

I am really hoping someone can help me out here

I am running a windows 2000 server with exchange 2000.

The server is partitioned as follows; C:\ 5.13GB, D:\ Exchange 49.2,
E:\ 49.7, 32.2GB unallocated.  I had the AV originally on C:\ but moved
it to E:\ this morning.  There is also a plug-in for exchange installed
as part of the AV suite.
Users can send ok, the problem is in receiving email.  I looked at ESM
and in POP3 current connections it shows a list of users trying to send
email

If I reboot the server, everything is fine for a while and then the
problem recurs.  There doesnt seem to be a problem with any of the
Exchange services, at least not in application or system logs.  Also I
set up a contact earlier and am forwarding email to it and that is
working ok...I have tried disabling the email scanner in order to rule
that out, same problem exists even when it is disabled.

Anyone got any thoughts on how to resolve this issue?

Hi 

How did you disable the AV scanner? Did you stop the service? I have seen some AV products cause problems when disabled but with service still left running.

Have you excluded the relevant Exchange Directories and files? as outlines in the following MS KB:

I am sorry I could not get to your question earlier, I am just in the process of changing jobs and relocating to another city (Sydney)
