Mail is also "bounced" by the resend script for various administrative reasons; these bounces are described in approve(1).
When a list owner observes that an email address consistently causes mail errors, the owner may use bounce to remove the address from the list and place the address on a special bounces mailing list.
bounce-remind, which should be run nightly by cron(4M), sends a message to each of the user addresses on the bounces list, on the chance that the mail error has been corrected. The message informs the addressee that their mail has been undeliverable and that they have been removed from one or more majordomo lists. It also instructs them how to unsubscribe from the bounces list and re-subscribe to the list of their choice.
bounce can also be used to expire addresses off the bounces list after a predetermined number of days.
If bounce is invoked under a name that contains ``unsub'' it will simply unsubscribe the offending address from the majordomo list; it will not place the address on the bounces list.
for example.
In any case, a configuration file must exist and must contain the names of the owner's lists, along with their respective passwords and the email address of the associated Majordomo server. The format of this file is given in the CONFIGURATION section of the approve(1) man page. The default name for this file is ~/.majordomo, and the same file can serve for both the approve and bounce scripts.
The bounces list, if it is used, must be created. It is like any other Majordomo list excepting that the priority of this list should be set to junk and its owner and sender should be nobody. Of course, the ``nobody'' mail alias must exist; it is should be set to /dev/null. That is,
This will spare the human list owner as well as the postmaster from having to deal with mail bouncing from the bounces list.
A cron(1M) job should be set up to run bounce-remind every night. bounce-remind must run on the same server as the bounces list; it mails a message to everyone on the list advising them that they have been removed from one or more Majordomo lists and instructs them how to get off the bounces list and back on the list of their choice.
bounce can only expire addresses if it has a copy of the bounces subscriber file, so this can either be run on the server occasionally by the Majordomo administrator or by a cron job. It can also be run remotely with a copy of the bounces file retrived by the use of the ``who bounces'' command to majordomo.
