How could the problem not be with the communication between 5.5 and
mailsweeper?  Are you not using mailsweeper as your smarthost for external
communication?  Do you have a firewall between 5.5 and mailsweeper?  What's
the routing topology?

Subject: [exchangelist] Host Unreachable error on Exchange5.5

We are running exchange5.5 with SP4, we use mailsweeper4.3 as our SMTP
gateway.  sometimes on certain emails with attachments, the emails queue up
in the outbound queue on the IMS with the decription "Host unreachable", I
tried to and other domains using the same email message and got
the same error.

the message doesnt even seems to be to mailsweeper, so not sure whats the
problem with these certain emails.

can anyone advice ?
