this may be a "want" item, but it may be doable in the context of exim as it exists now. i haven't really looked at it closely enough to see if it's feasible with 1.9x as is.
VERP support, as described at
ftp://koobera.math.uic.edu/www/proto/verp.txt
would be a very nice feature for handling bounce messages for large mailing lists...
has anyone looked into this?
