Debugging Header checks in sendmail 8.9

Last Update 1999-02-13

The AcceptMAIL ruleset for the header checks makes use of the macros ${client_name}, ${client_addr}, $f.

Let's assume the following: you use the access map, with entries like:

134.245.15.1			OK
informatik.uni-kiel.de	OK
postmaster@aol.com		OK

, and an IP address which is not in your map is 1.2.3.4, with an associated hostname example.com (this isn't correct, but you need to use IP addresses and hostnames according to your local configuration anyway).

e-mail from a friend:

sendmail -bt -d21.4
> .D{client_addr}134.245.15.1
> .D{client_name}informatik.uni-kiel.de
> .Dfpostmaster@aol.com
> CheckTo friend@public.com
> CheckMessageId abc

and other tests, which should be accepted.

e-mail from someone else

sendmail -bt -d21.4
> .D{client_addr}1.2.3.4
> .D{client_name}example.com
> .Dfsome@example.com
> CheckTo friend@public.com
> CheckMessageId abc

This should cause an error.
