I'm looking for a dead simple mailing list (unix friendly). Robustness, fine-grained configurability, "enterprise-readiness" (whatever that means) are not requirements. I just need to set up a tiny mailing list for a few friends. Rather than hack something up myself, I was wondering if anybody knows of anything already out there with a similar goal?
I should note right now that I don't want an externally hosted mailing list -- it needs to be software I can install and run on my server. I know of many places I can host a mailing list at (Google/Yahoo groups), but it would be nice to keep the data local.
