Exchange 2000 to 2003 routing over internet

I have a need to host mail for a particular domain name (xyz.com)(on exch
2000) and the immediately route email to my client's server (exch2003). The
important part is here, I need the email to remain in the Information Store
(user's mailbox) for a 10 seconds or so that it may be scanned by Symantec
antivirus.

By just routing via smtp, the Symanect AntiVirus filtering for exchange will
never scan the message.

Any ideas??

I have taken care of situations like this by changing the default inbound
port for Exchange to 9025, rather than 25. I then install Symantec SMTP
Gateway on port 25. This means all inbound mail goes through Symantec SMTP
Gateway before it ever hits the Exchange server. Since Exchange 2000 and
above natively talk SMTP, I have not been thrilled with this particular
solution, since administrative messages are passed between servers via SMTP
and this puts your antivirus solution in the middle.

Better yet, use a SMTP gateway as a front-end for all inbound email (such as
Symantec SMTP Gateway--contact your Symantec rep--you may already own it).
All email from outside of the company is sent directly to a server running
only Symantec SMTP Gateway (or other non email programs, as well). The
antivirus program acts as the SMTP server, accepts the email, scans it, then
delivers it via SMTP to your Exchange servers. This way you are using the
antivirus server to route email in and out of the company.

When I have talked to Symantec, they told me that Exchange does not put
messages into the Exchange Information Store, so it does not scan the
messages when they are routed through a server to another Exchange server in
the organization. This dramatically improves routing performance as
compared to Exchange 5.5, which, I believe, did put the message in the IS on
the way through.
