''FEATURE(compat_check)'' '''


Screen sender/recipient pairs V8.12 and above

Beginning with V8.12 sendmail, it is possible to screen email based on sender and recipient address pairs stored in the access database. One use for such a method might be to prevent one employee from receiving mail from another employee. Another use might be to prevent a pseudo-user, such as admin, from receiving spurious reports from another user, such as bin. Yet another use might be to reject spam mail to a mailing list.

This compat_check feature is described in full in Section 7.5.7.
