How to bind imap to 2 interfaces

[Tornoci Laszlo]

Hi,

I have a server with eth0, eth1 and localhost network interfaces. I want 
to have cyrus to service imap on eth0 and localhost, but NOT on eth1.

After reading man cyrus.conf, I can make cyrus to listen on all 3 
interfaces:
   imap          cmd="imapd" listen="imap" prefork=5
or just on one of them:
   imap          cmd="imapd" listen="localhost:imap" prefork=5

How to make it listen exactly on localhost and eth0?
