Portsentry and Sendmail

[Matthew Carpenter]

I typically will use SMTPClient (fm:smtpclient) in these situations.  It
allows more control than "mail" and one option is to tell it which SMTP
server to use.  It does NOT require sendmail and you can point it directly
at your SMTP server inside.  This, along with the fact that you can
specify the sender's name, has kept SMTPClient high on my "Kewl Tool"
list.
Instead of "root at firewall.me.com", you can get email messages from
"Firewall at me.com" or something to that extent.
