Setting up a connector to send E-mail out from a different IP address

All,

A few months ago, due to having an open relay up for POP3 accounts with our Field Staff, we ended up on a blacklist of Yahoo's and were unable to E-mail the domain. We're off now but are still having problems e-mail yahoogroups.com. We've tried everything with Yahoo and they've been uncooperative. I've done some digging and need help with the following:

a three server network:
Server Alpha - a domain controller and does our DNS and DHCP
Server Beta - is our Exchange 2003 server and is also a domain controller
Server Delta - is not a domain controller but is a member and opperates our Wireless Device push client as well has our network printers installed on there (Wireless Sync by intellisync)

We use 2 of our 4 external IP addresses, one goes from the router to the switch to server alpha the other goes to the router and we use a one to one nat on the router to connect the interal IP of Server Delta to an external IP (required for WSES software).

I've done a little reading about using Exchange Connectors to send E-mail out over a different server connected to a different IP, does anyone have any idea or help they can offer me?

indeed you will get blacklisted after only a few weeks of having an open relay.  Are you sure it is secure now? The answer to your original question is to program your router to operate on the new IP address.  This may not solve all email blocking issues, and for pickey domains you should create a smtp connector pointing at your ISP's mail server.

Confirm that taking this step will help you email yahoogroups by configuring a mail client like OE and sending email via the ISP SMTP server, if it makes it, you are ready to go with a SMTP connector.
