[SA-exim] memcached for greylisting

[Eduardo Diaz Comellas]

Hi!

In the exim users list it has been proposed to use memcached to store 
some values. As memcached implements record expiry natively, and can be 
easely shared in a network, it seems to be a great  option for greylisting.

This is the original post:
