Exim outgoing ip rotator

     This is a patch for Exim that makes it use an ip pool for outgoing emails. After this patch will be applyed to exim's source code and exim will be compiled and installed/configurated all you have to do is put the ip's you want to use in a file ( each on a line ) and it will use all of them for outgoing emails.
This patch rotates the ips so that for each new outgoing email it will use another ip from the pool. The ip pool is very easy to manage as it's just a text file containing ips that can be modified ( for adding/removing ips ) at any time, without even having to restart exim in order to apply the new ip pool.
This patch is also available for Postfix and Qmail
