compat_check FEATURE
The compat_check FEATURE in sendmail
allows discarding, temporarily failing, or permanently rejecting mail
based on an envelope sender and envelope recipient combination.
compat_check is used in conjunction with access_db. FEATURE(access_db) must appear before FEATURE(compat_check) in your sendmail macro configuration file. Place compat_check rules in the access database (i.e. /etc/mail/access).
Example
Mail from the envelope sender user@example.com to the envelope recipient bhutch@gmail.com will be discarded.
Compat:user@example.com<@>bhutch@gmail.com DISCARD
Note: if this message from user@example.com was addressed to multiple envelope recipients, only the message to bhutch@gmail.com will be discarded. Other envelope recipients will receive the message.
