[lug] Distributed e-mail lists

[John Hernandez]

I'm looking for a distributed e-mail list (with support for parallel mirrors) for a high volume list.  It needs to support Linux and centralized subscription management.  What we need is basically a system that delegates portions of the subscriber list to different MTA's transparently and queues outgoing mail in parallel.

So far, I've seen ezmlm-idx w/ qmail.  Any other open source solutions out there?
