It doesn't look as if it would be of much benefit to you. Setup is
fairly simple, although it's worth a Google for the specific ISP you use
(obviously not in your case) to get the configuration file right
quickly. It defaults to passing the mail to port 25 of localhost, but
can be told to send to any SMTP server. It can collect by POP3, IMAP and
a few more obscure protocols if I remember rightly.
It's useful to avoid the port 25 hole in your firewall, and also with
broken ADSL routers which NAT without port forwarding, thereby not
permitting incoming connections (BT Openworld in the UK supplies such a
router with its Ethernet ADSL package).
