NAME

ezmlm-warn - send out bounce warnings

SYNOPSIS

ezmlm-warn [ -dD ][ -t timeout ][ -l lockout ] dir

DESCRIPTION

ezmlm-warn sends out warning messages for the mailing list stored in dir.

ezmlm-warn scans dir*/bounce/d/*** for directories older than timeout days ago (see -t). The directories are created by ezmlm-return and contain bounces. If ezmlm-warn sees a distribution bounce for box*@domain received more than timeout days ago, it sends box@domain a list of all the message numbers missed recently, and deletes the bounce. If it sees a warning bounce for box@domain received more than timeout days ago, it sends box@*domain a probe, and deletes the bounce.

ezmlm-warn uses dir*/bounce/lastd*** to keep track of when it was last run. If insufficient time has passed (see -l) ezmlm-warn exits without further action.

ezmlm-warn keeps files with the bounced message numbers in dir*/bounce/h***. Expired files are removed and dir*/bounce/lasth*** keeps track of the last subdirectory scanned.

ezmlm-warn will not send a warning or probe to an address that is not currently a subscriber.

If neither the -d nor the -D option is given to ezmlm-warn, it will process bounces for both the main and digest lists.

ezmlm-warn reads dir*/copylines*** to determine how many lines of the original message to copy into the outgoing message. If this file is empty or not present, a value of 0 is presumed, meaning that only the header is copied.

If dir*/nowarn*** exists, ezmlm-warn exits without taking any action.

ezmlm-warn uses ezmlm-queue(1) to send messages. ezmlm-warn sets environment variables from /etc/indimail/ezmlm/global_vars. This can be used to set queue related variables for ezmlm-queue

If /etc/indimail/control*/qmqpservers*** exists, ezmlm-warn will use qmail-qmqpc(1) to send messages. Server IP addresses listed one per line in /etc/indimail/control*/qmqpservers*** will be tried in order.

OPTIONS

-d
process bounces only for the digest list. Digest list bounces are stored in dir*/digest/bounce/*** rather than in dir*/bounce/***.

-D
Process bounces only for the main list.

-l lockout
ezmlm-warn will abort execution if it was run less than lockout seconds ago. The default is timeout / 50, which with the default timeout is 20,000 seconds (approx. 5.6 hours). There is no reason to use this switch, except for testing and possibly in combination with -t.

-t timeout
Bounces received more than timeout days ago are processed. This overrides the default of 10 days and may possibly be useful for very large busy lists. Also, a timeout of zero can be used to send a warning to all addresses for which a bounce has been received and a probe for all addresses for which a warning has bounces. This is useful to rapidly clear out bouncing addresses from a (low quality) address list.
