Anyone interested in cosponsoring work on a tighter integration of Plone and Mailman?

Rob's point on the ZODB is well taken, but there are some other
considerations for large lists that may make specialization desirable.
A good large list manager does things like SMTP aggregation (pulling
together destination addresses for the same MX and submitting them in a
single transaction); setting VERP headers that work with the SMTP agent;
retrying local addresses; automating bounce handling, scoring, and
subscriber deactivation; maintaining a queue that may need to be
processed over days; etc.
