Good day, we have 2 mail server, one with antispam/antivirus services and another one without them, both with postfix and another server with mysql db backend storing login/password. We are happy with this, but needing to increase performance, we are looking for load balancing solutions. The first wat I was thinking about, is to move the storing from the servers to a single NFS server, and use the mail/pop3 server just as "engine" that check login/password on the mysql db and access data in the NFS and load balance with dns round robin through the various servers I can use as frontend. The uplink is a 34Mbps so I don't think NFS is a problem for performances. Servers are different, the antivirus/antispam is only for receiving, while the other(s) is(are) for both receive and send. Do you think this would be a good solution ? Is there a better solution than round robin (ie, perdition or iptables with DNAT based on stattistical redirection) ?
