(2nd Request) Disable scanning for a client that connects via SMTP-AUTH

[Jeffry Page]

I have done this using MIMEdefang and a custom function for mailscanner. I
have it currently setup for sendmail.

I had to do this because mail I sent from my home machine via SMTP would get
flagged on the spamhaus-ZEN RBL, which any home internet IP should. I really
wanted to use this RBL so this was the solution. It feels kind of hacky the
way its done, but it works really well and is totally transparent.

I looked it up and mimedefang is only for sendmail, but if you have a way to
add a customer header in on other MTA's then it would work for this also. I
only used MIMEDefang to add a header in before mailscanner got the email.

In which case please tell me how I find out from the email headers, in 
such a way that it works for all 4 supported MTAs. I'm not interested in 
a sendmail-only solution.

Thanks,
Jules.
