Yesterday, I published an article about majordomo and my conclusion of nut using it, since the version my webhoster provides does not support archives and digest functionality. But do I need it actually?

I think that the mailing lists will have only a very limited number of users and, hence, only a small amount of traffic — digests are not neccessary.
Archiving – I will find a work around.

The only remaining question is if there are important security issues which are not avoided by my configuration. Anyone seeing a problem there, feel free to comment here!
