Page 512--513 of the Second edition of "Sendmail" by Costales and Allman,
O'Reilly, 1997, Section 29.10.4 The check_compat Rule Set.
Not all situations can be resolved by simply checking the recipient
or sender address. Sometimes you will need to make judgement based
on pairs of addresses....
Other uses for the check_compat rule set might be the followwing
...
* Screening a particular recipient to prevent that user from
receiving objectionable mail form a specific source.
I gave away my copy of the first edition (cpright 1993), but I believe
it gave a similar example, but using the checkcompat() routine. If any
list members have a copy of the first edition, please post.
