New secondary exchange server not recieving email - Sends fine - primary sends and recieves fine.

Hello.  I have a question that is boggling my mind.

We currently have an existing exchange 2000 mailserver running on Microsoft Server 2000.  This is set to forward all mail to a RedHat EL server (hereby referred to as G1 for gateway1).  As such, we have the in place server (hereby referred to as S1).  In exchange system admin, we have an SMTP connector set to forward all mail to our gateway using an IP in brackets [xxx.xxx.xxx.55].  This setup has been in place for over a year and works perfectly fine.

Well, because of mailbox bloat (despite a nazi-esque "we're going to delete email after 30 days" policy) we have gotten too close for comfort for our current 1 server setup.  So, I am tasked with bringing another Server2k exchange2k server online until we migrate to the new servers next year (hereby referred to as S2).  

I have exchange2k installed and I have migrated my test account "ahab.quiquaig" onto S2 and have gotten strange errors from the server.  I can send email out of the server, but from the headers, it takes a completely different path. As well, I can send out email, but I can not receive email from the outside INTO the server S2, but it works fine on S1.

My suspicion after reading http://support.microsoft.com/kb/294736, it says not to have SMTP connectors set up on a virtual server (which is set to be S1) unless you only send email OUT and not to other servers.  As well, I suspect that my virtual exchange settings are jacked up as well because I can not get the public folders to replicate from S1 to S2.  On the replicated folders status it says "In Sync" on S1's status, and "Local Modified" on S2's status.  It seems like there is only a one-way flow of information from S2 to the outside world.

What do I need to do to get my mailflow to work this desired way:

Outbound email (sent on a profile from S2)

S2 -> S1 -> G1 -> Inet -> end point

Inbound email (sent to a profile on S2)

Sender -> inet ->G1 ->S1 ->S2

????

Do I need to install a new server to be the "virtual server" so I can have the SMTP connector on S1?  It's not possible to remove the SMTP connector because we need to funnel email in and out of our redhat box for spam and sendmail functions on our Linux gateway.
