SYNOPSIS

ezmlm-checksub [ -nN ] [ -m MESSAGE ] dir [ subdir1 ... ]

DESCRIPTION

ezmlm-checksub 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-checksub exits with an error.

If -N is set (the default) and SENDER is not on any of the mailing lists, ezmlm-checksub outputs the message named TXT_ONLY_SUBSCRIBERS and exits 100, indicating a permanent failure to qmail.

If -n is set and SENDER is on any of the mailing lists, ezmlm-checksub outputs the message named TXT_REJECT_POSTS and exits 100.

Otherwise, ezmlm-checksub exits with a zero exit code (success).

If subdir1 (or more) are present on the command line and are relative paths, ezmlm-checksub only examines the named subdirectories within the absolute path dir.

ezmlm-checksub exits 111 on errors.
