Inteface/Address Binding

[Matt Prigge]

I hope Im not asking a ridiculously stupid question here, but is there a way
to tell cyrus to only bind to a specific IP address and/or interface? I
suppose I could accomplish this with kernel filtering (something I am using
anyway), but I would think cyrus would have some sort of config option for
this (most likely part of the listen= statement in cyrus.conf).

Thanks!
