ezmlm-issubn(1)ezmlm-issubn(1)NAMEezmlm-issubn - test to see if an address is subscribed to a mailing
list
SYNOPSISezmlm-issubn [ -nN ] dir [ subdir1 ... ]
DESCRIPTIONezmlm-issubn checks to see if the address obtained from the environment
variable SENDER is subscribed to the mailing list stored in dir/subdir1
or the mailing list in dir/subdir2 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(s). If SENDER
is a subscriber, the action line is executed, if not, the line is
ignored without the generation of an error condition. To generate a
fatal error, just:
|/path/ezmlm-issubn
dir ...
|| (echo "err msg"; exit 100)
|/path/action_for_subscribers
|/path/more_for_subscribers
ezmlm-issubn exits 100 on permanent and 111 on temporary errors.
OPTIONS-n Negate exit code. Exit 99 if SENDER is a subscriber and exit 0
if not. This is useful when trying to exclude SENDERs.
-N (Default.) Normal exit codes: 0 is the address is in any of the
lists, 99 if not.
NOTES
The use of ezmlm-issubn is deprecated. Use ezmlm-checksub instead.
To maintain backwards compatibility, if dir1 (or more) are present on
the command line and are all absolute paths, ezmlm-issubn examines each
of the directories for the sender. Otherwise, it only examines the
named subdirectories within dir.
