That's not really a function of the MDA. Your MTA should be doing
that sort of thing. Cyrus might do that sort of thing, I don't know,
but it's not likely. Cyrus just delivers mail to the end user. It
doesn't do any transport.
Think of it like this:
Your friend sends a large package to you via freight. The truck
can't come into your neighborhood, so it drops it off at a
distribution center. The smaller truck from the distribution center
delivers the package to your door. Think of it like FedEx or UPS.
They have 18 wheelers and jets which take the packages the long
distances. Those are the MTAs (like exim, sendmail, postfix, etc.).
The trucks you see in the neighborhood double-parked so you can't get
by are the MDAs (like Cyrus, UW, Dovecot, Courier, etc.).
That mail forwarding thing is sort of like a change of address form.
The mail/package gets routed to the new place before it ever sees the
local delivery truck.
