If you need bounce info, and if that list is re-used after opt-outs are
calculated, then you need a mailing list manager. That's because it
injects messages one at a time, so you can tune it to not hammer a
server, which is bound to reject a single message with 50,000 Bcc:
recipients (RFCs don't require an MTA to even accept delivery of such a
message, and it's going to kill the upstream MTA)
You're also going to need the bounce usefulness of mailman, but it's
only really useful after multiple sends. One send cannot remove bounces
from the list in case the bounces are non-permanent. No doubt you could
hack something to get rid of permanent looking bounces but you'd have to
parse the bounces yourself then. Not easy, when MTAs can respond in all
sorts of languages and with all sorts of codes.
You don't want to be overwriting each time, if I'm reading between the
lines. You want to *synchronise* with other lists each time. For that,
you can use some scripting of your own in PHP perhaps to do this. I host
a site with a mailing list of c. 12,000 subscribers which are also in an
SQL database which synchronises with mailman at each change. It was a
hassle (auto-ftp and stuff) but it works nicely. I use tools in the
$prefix/bin directory of mailman like add_member, remove_member, and the
sync_can't remember the rest thing.
