Well, it's pretty easy to use a mail forwarder such as SMAP in the TIS
firewalls toolkit. If your firewall is unix you can replace the sendmail
daemon with this program which is short enough that you could actualy figure
out what the code is doing.
The traditional argument is that if the program is complex enough that you
can't tell what it's behavior will be, then there is a high risk there is a
hole in there which you don't know about.
