[nsp] pix and mail servers

[fingers]

what some people do, is have a "trusted" mailhost outside the firewall,
get it to relay the mail to the "secure" mailhost inside the firewall, and
only permit that single host through.

I've seen many many mails of people who say mailgard is horrid.
personally, I've never had a hassle with it. perhaps those more
knowledgeable could specify which part(s) of mailgard break, which rfc
they go against, or how in general it breaks delivery of mail when
enabled?
