On the other hand installing a FreeBSD system with QMail/Procmail and/or
PostFIX for the other stuff is a no-brainer especially with a Webmin
Management front end.

Alex there are many email systems out there - but make sure that
whatever you buy can support NTPv4 and not SNTP or unauthenticated NTP
since this is how the GW is going to be able to put time-marks on
receipts which must have legal authority.

So that means any appliance system provider must have at least NTPv4
tested with both Autokey and symmetric-key and the new interface
specific ACL's in the 4.2.6 versions of NTP. Further the issues of the
ECC/Parity memory become important here because time is moved over UDP
and is subject to single-bit errors all over the place.
