Outbound email shows Border Manager public IP

[bobcatfv]

Running GW 7.0.3 server, NW 6.5SP6, BM 3.8
Sometime in early March, my mail server was failing, and outbound emails began showing there was a Reverse DNS issue. Turns out our public IP for our email was now showing to be the public IP for Border Mgr.
On 3/18/09, a new Novell email server was installed, with the correct public IP, but outbound emails still show the Border Mgr one.
I don't know how to track down why it happened, or better yet, how to fix it and understand later.
I read through the helps, but I don't know how to do most of what is talked about. I use ConsoleOne, but apparently barely from the articles I read!
Several other things that have occurred:
1. We switched our webpage over to a different company in late January, and had our ISP crate an A record to point to the new IP (which I've been told has nothing to do with this issue), and
2. Our ISP added a pointer for our BM IP, indicating that it still wouldn't answer as mail (which I don't want it to anyway!), and
3. Yesterday I was out, and something happened (I don't know what), but our district lost GW email function for awhile, and also internet capability. I don't know what my mgr did to restore it, but got it going. When I stopped by last night, the servers were out of timesync, so I got that sync'd.
4. As of yesterday, we can no longer log into our webmail interface; we get the message "Unable to communicate with GroupWise WebAccess agent".

It's going from worse to "worser". :-(

Can anyone help me?

Thanks, in advance, for being so nice to this "Novell dummy". I hope I'm your only one.
