Tom is right on this one, likely due to my lack of clarification. We're
using exim for more of a distribution list server here, not as a
traditional MajorDomo or Mailman setup where list members can e-mail. We
just need a way to send out e-mail to our DynDNS users when we have system
status updates, announcement, newsletters, etc. (And its not spam, no, not
at all!)
So, Tom's suggestion fixes the problem, cool. Back to my original
followup: is this the best way to do it? (using a redirect router with a
large redirection file, having exim re-write envelope-from for VERP) Or
should we be manually submitting each message to exim for delivery,
pre-VERP'ed, etc?
Mailman and MajorDomo are not options here, they are just way too
heavyweight for this application.
