routing to multiple smtp virtual servers

[kandym]

My exchange server hosts several domains, and I'm having some issues routing messages to the appropriate SMTP virtual server. The first problem I'm having is that even though I've created an SMTP virtual server on its own IP address for each domain, the virtual servers are all redirecting messages through the first SMTP server I set up (was the default SMTP Server until I renamed it). They're acting as if they're configured to use the first SMTP server as a smart host, though they're actually configured identically to the first SMTP virtual server.

Has anyone else had experience with multiple virtual SMTP servers? Essentially I want each virtual SMTP server to deliver mail for the appropriate SMTP domain independant of other SMTP virtual servers on the Exchange server.

Update on this - after leaving it alone for a few hours, I came back to it and found that my virtual SMTP servers are now sending email without routing through the primary SMTP server, but they won't bind to the IP address I've set on the SMTP properties page. So, if I send a message through one of the new SMTP virtual servers, it sends just fine, but it sends over the wrong IP address. Does anyone have any tips on configuring multiple SMTP servers, each on their own IP address?
