Description:

This package installs couriermlm - a mailing list manager for the
Courier mail server. If you do not need the ability to manage mailing
lists, you do not need to install this package.

couriermlm is used to set up, maintain, and run a mailing list.
couriermlm automatically processes subscription and unsubscription
requests, and removes undeliverable addresses from the subscription
rolls. Mailing lists managed by couriermlm require zero human
administrative oversight. couriermlm supports digests, write-only
posting aliases, and moderated mailing lists.
