This is fairly trivial to do with Exim by storing your acl entries in a 
database or directory with a field/attribute for expiry, and an 
appropriate router configuration. No doubt you could implement this 
using a small script for any MTA. The upside of using a db/ldap backend 
is that it makes it easy to inter-operate with other things like your nms.
