We just had to change server locations and were forced into using virtual domains rather than dedicated IP addresses.  We don't have a lot of customers who use the old webmail, but it only takes a couple to reveal a problem I have not been able to figure out a solution for.  The g_webmail_port only provides one port for the server for webmail.  All the domains on a particular IP address thus seem to be coming in with the wrong domain except anyone who is on that particular domain and I have no idea why it defaults to that domain.

So when someone goes to login from myserver.com:xxxx they see the window showingHIDDEN@main.com and are unable to log in because THEY are not users on hisdomain.com

I can't find any way to separate this nor to assign specific ports for each domain, if that is possible.

Does anyone have  a solution to this?

We have one bunch of domains set to one address and another bunch set to another just to split them out and not have everyone pile onto the same IP at once when sending/receiving email.

Please, does someone have an answer to this?

Is URL host set for these domains?   In the web admin, under the domain Settings for the domain, 'Mail host A record name', I setup mail.<thisdomain>.com for each domain and instructed users to go to http://mail.<thisdomain>.com

I would not assign ports.  Leave everything on port 80.

There is also a file called surgehost.ini that has an effect on this.  I don't have access to my notes other than I seem to remember a tellmail command to rebuild surgehost.ini file.
