Routing and Delivery between 2 sites servers with mailsweeper on one site, how?

Two Locations: HQ and Site#2

HQ -   Site#2 -

Exchange 5.5 plus mailsweeper 4.3_17 at HQ

2nd exch 5.5 server at site#2

placed new servers at each site running 2003 r2

on those servers is ms virtual server 2005

on each is a virtual machine, msexch01 at HQ and msexch02 at site#2

in these VMs is win 2003 r2 with exchange 2003

the first of these exchange 2003 servers was created at HQ and given the ip of the mailsweeper as a smart host

the second build at site #2 and can see msexch01 on the network

each site has a cisco asa firewall

issue #1 - msexch01 cannot deliver mail to msexch02, but can receive from it.

issue #2 - msexch01 can send to mailsweeper, but incoming is not appearing, yet mailsweeper is working fine

i think it may be routing groups and/or smtp setup. or bridgehead options

not too familiar with these , done mostly standalone setups.

any suggestions ideas as to how or examples?

when i run the best practise analyser : for exch 2007 it tells me the "Routing group servers are in different AD sites"

any suggestions as to how to have 2 exchange 2003 servers talk and deliver to each other and have msexch01 then send and recive internet mail to/from mailsweeper?

or another question may be do i have to create (a) routing group(s)?

or should it not auto deliver between each other using Active Directory info?

End result on this was to create the SEND conector to a smart host in our case mailsweeper

no extra connectors other than the default required as Active Directory does the lookups for delivery

1>. run forest prep and domain prep on the schema master
2>. prepare the legacy permissions
3>. prepare the domain etc..
4>. install exchange on the new hardware primary site with mailsweeper
5 config send connector
6> install on 2nd site server

migrate the mailboxes across using the management console
