This patch allows you to define sender+recipient exception pairs in
greylist.conf. The syntax is the same as existing "from" clause, but you
can put an additional destination recipient match on the end after a
comma. E.g.
from remoteuser@...,localuser@...
The 2.0 revision patch also lets you specify destination inside the regex
escape, separated by a comma. In this case both from and recipient must be
valid regexes, e.g.:
from /remoteuser@.*\.domain.com,localuser@.*/
