This pages describes a method for e-mail to work with using a single mailbox with multiply domains. Does anyone know how this is done? FutureQuest seems to be the only place to do e-mail this way. I would like to figure out how to get this setup on a dedicated server.

Looks like they are creating alias's ....

I have a client who does this .. combining his mail server with paltypus ... I can't remeber what serfver he uses tho ...

I believe that FutureQuest just uses qmail, which supports that.

They're definitely not the only ones who do that. But they do seem to be the only ones calling it IRM/IRO.

Sendmail can do that too, though.
