If you are interested in things "under development":
CVS version of cyrus implemented socketmap protocol which will be handled by
sendmail 8.13 [
http://www.sendmail.org/8.13.0.PreAlpha4.html ]
In Exim terminology: single-key lookup passed via TCP based protocol to an
external process.
Based on discussion in info-cyrus@??? it will be no problem
(from cyrus perspective) to add quota check (e.g. based on SIZE= from "MAIL
FROM: command.)
The socket map protocol is very simple so it may be implemented by exim some
time in the future.
