bounce, bounce-remind - handle majordomo list subscribers whose mail is
bounce [-d] [-f config-file ] [-majordomo server-address ] [-unsub]
bounce [-d] [-f config-file ] [-majordomo server-address ] -expire
[-maxage days ] bounce-address-file
Provided with distributions of Majordomo.
bounce and bounce-remind are perl scripts which help list owners handle
subscribers whose mail is bouncing. Mail is "bounced" in this context
when it is undeliverable because hosts or addresses are unreachable or
because of other mail errors.
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 unsub-
scribe from the bounces list and re-subscribe to the list of their
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 sim-
ply unsubscribe the offending address from the majordomo list; it will
not place the address on the bounces list.
These options relate to bounce; bounce-remind takes no arguments or
-d Debug; print what would be done, but don't do it.
Use the specified configuration file. The default is
~/.majordomo, and the format for this file is described in
the CONFIGURATION section of the approve(1) man page. This
file provides the list-owner's password for each list and the
address of the corresponding Majordomo server.
Use this server-address for majordomo rather than the address
from the configuration file.
-unsub Unsubscribes the offending address from the majordomo list,
without entering that address on the bounces list. This is
equivalent to invoking bounce under a name containing
-expire Expire entries from the specified bounces list.
Expire entries older than days. The default is coded into
the bounce script as $default_maxage days. It is set to 21
days in the majordomo distribution.
The list from which the offending user-address should be
The address to which mail is currently undeliverable.
The name of the file that contains the bounces list.
If bounce is going to be used only to unsubscribe users, a link can be
created whose name contains ``unsub'' so that users could be unsub-
scribed simply by typing
unsub firewalls-digest firstname.lastname@example.org
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.
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 sub-
scriber 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.
