Horde/IMP and multiple domains
 

I don't know if anyone on these boards uses Horde and IMP for their webmail. I have a server I am trying to set up such that folks from multiple domains. I've got Postfix set up to recieve the mail, the MX records are appropriately setup too, I just am trying to set up a single IMP installation to handle multiple domains.

In other words, when someone goes to

<http://example.com/webmail/>

mail will be sent from username@example.com, and when they go to

<http://example.net/webmail/>

mail will be sent from username@example.net.

I'm using IMP 3.2. According to the Horde FAQ, it is possible but they don't have any directions for doing so. Anyone here have an idea?

Assistance
 

Anyone have a clue or can at least point me in the right directions?
