Looking for free software recommendats for managing a few small mailing
lists.

Typically these will be for small groups of about five to twenty
subscribers, averaging one to five messages a day.

Especially desired: simplicity and small footprint software.

I'm currently using entries in /etc/aliases to accomplish this, but
this is too simplistic. Reply-to-list doesn't work because there are
no list headers.

Am currently using postfix.
