ezmlm-issubn - test to see if an address is subscribed to
a mailing list
ezmlm-issubn [ -nN ] dir [ dir1 ... ]
ezmlm-issubn checks to see if the address obtained from
the environment variable SENDER is subscribed to the mail-
ing list stored in dir or the mailing list in dir1 or ...
If SENDER is not defined ezmlm-issubn exits with an error.
If SENDER is on [any of] the mailing list[s], ezmlm-issubn
exits with a zero exit code.
If box@domain is not on the mailing list, ezmlm-issubn
exits 99. This exit code is non-success from a shell point
of view, but to qmail it means "success and skip remaining
lines in the .qmail file). Thus, a simple way to execute a
delivery if the criteria are met is to place the ezmlm-
issubn line first, followed by the action line. If SENDER
is a subscriber, the action line is executed, if not, the
line is ignored without the generation of an error condi-
tion. To generate a fatal error, just:
|/path/ezmlm-issubn dir1 ... || (echo "err msg"; exit
ezmlm-issubn exits 100 on permanent and 111 on temporary
-n Negate exit code. Exit 99 if SENDER is a subscriber
and exit 0 if not. This is useful when trying to
-N (Default.) Normal exit codes: 0 is the address is
in any of the lists, 99 if not.
