NAME

ezmlm-issubn - test to see if an address is subscribed to a mailing list

SYNOPSIS

ezmlm-issubn [ -nN ] dir [ dir1 ... ]

DESCRIPTION

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 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.
