Most greylist software only whitelists for a specified period of time,
typically 24 hours.  YMMV of course.

I don't think that's necessary, although it makes the situation
clearer.  What I'm recommending is switching the PTR for the IP
address to point to mail.seaplace.org.

I suspect that if you change Mailman to talk to localhost:25 instead
of mail.seaplace.org:25, Amavis will no longer be called.  It's
probably possible to get Postfix (IIRC) to recognize mail.seaplace.org
as localhost, and that might fix it too.  But at present, Postfix is
probably configured to think of mail from local host as trustworthy
and not scan it on the way out, while mail received on the external
interface is treated as "external", and therefore as needing scanning.
