[Mailman-Users] Question re: interfacing list with MySQL and message throttling

Justin,
  your requirements sound like Ezmlm (with the Ezmlm-index patches
which among other things provdes a MySQL interface) would be the
best solution for your needs in terms of currently-existing software.
Ezmlm reuires Qmail as the MTA; there are some (relatively obscure)
Qmail tricks that allow you to do the rate-throttling you want.

> if a proprietary solution would have to be developed

One of the big drawbacks of Ezmlm is that it doesn't come with a
genuine Free Software license, so it'll have to be classified as
"proprietary" (even if its licensing situation not nearly as evil as
with most other proprietary software).

If this bothers you, you could sponsor the development of performance
enhancements for Mailman that will make it very suitable for
situations like you describe.

This kind of thing needs to be implemented in the MTA... maybe Mailman
should come with a special-purpose MTA?  (One which does only the
first round of delivery attempts for any given message, with per
recipient host rate-throttling, and while doing this using the disk
only for journaling... actually I probably should have proposed this
on the mailman-developers list.)

Greetings, Norbert.
