I have a copy of the first edition of Sendmail, (c) 1993, printing histry
shows :November 1993: First Edition, Feb 1994: Minor correction, Sept
1994: Minor corrections.
The only instance of checkcompat() in the index points to pg 191, where
they discuss the code for the function in conf.c.
"Inside conf.c is the often overlooked routine checkcompat(). It has
existed since Version 3, and is intended to allow the site administrator
to accept, reject, and log mail delivery attempts. It contains coments
describing one way to code it. In this section, we provide three other
examples of ways it can be used."
They do document the most interesting variables include user and host
portions of the recipient, the IP of the sending host, the name of the
sending host, and the sender information.
They show examples of code for the following scenarios:
Accept only mail from our domain
Refuse to act as a mail gateway
Limit size of guest messages
Nothing specifically about using it to make decisions based on both sender
and recipient. Bummer, it would be nice to rub their nose in an older
prior work, but it sounds like 2nd edition might do the trick
