Major Major Mailinglist manager for OS/2

Major Major is a mailing list manager for
OS/2 and eComStation. It lets you create multiple
mailing lists on your machine. People can subscribe
to these lists by mailing a "subscribe" command
to Major Major. (There is also an "unsubscribe"
command.) You can also subscribe/unsubscribe people in your
role as system manager.
To make this work,
you have to be able to create e-mail
accounts. You need one e-mail account for Major
Major itself, plus one per list that you
host. This means that you need to have
access to an e-mail server. You can install
an e-mail server such as Weasel email
server for OS/2 on your own computer. Alternatively,
you can use the e-mail server of your
ISP or other mail provider, and ask that
provider to create the appropriate accounts.
