[imp] Multiple domains on IMP

[Mario Gamito]

Hi,

I'm running a mail server with about 50 different domains.
All with the same IP.

Well, i've instaled horde/imp and i can work just fine with the domain
that is defined both in Apache and in horde/imp.
Let's call it domain1.com
So, i work just fine in http://mail.domain1.com

But i also want IMP to work fine the same way with http://
mail.domain2.com, http://mail.domain3.com ... http://mail.domain50.com

Is the only way setting up 50 Virtual Domains in Apache ?
There's no workaround in IMP for it ?

Any help would be appreciated.

Warm Regards,
Mário Gamito
