Dear all,
I have a Centos 5.2 server with Postfix 2.5.6. which handles mail for a
couple of websites (virtual_mailbox_domains).
Following Yahoo's and other ESPs suggestion, to send mail from different
IPs, depending on their function, I would like to use 3 IPs (already set
up on the server) to send out emails and also would like to sign them
with both DKIM and Domainkeys.
Based on your experience, I kindly ask for your suggestion, what would
be the best solution to achieve this, considering the performance of the
mail server.
