I have a CentOS 5.5 64 bit mail server running Postfix. I want to do load balancing of mails sent/received to this server.
My Postfix MTA will relay mail to other two servers who will perform the SMTP service to send or receive mail messages.
Can anybody help me with this?

You can try haproxy in TCP mode. I tried it before to load balance incoming SMTP traffic on several SMTP servers (postfix), and it worked fine. You can also allow connections coming from specific IP addresses only if applicable in your case.
