How can I setup a Sendmail server pair/farm in order to achieve load balancing and failover function ?
Say, if I wish to deploy sendmail in a large corp (2000+ users), I don't possible expect a single sendmail server can do all the job, so, I'm thinking of a sendmail server pair (or farm).
But I'm not exactly sure on the detailed direction..., should I dig into :
1. linux clusters ?
2. sendmail settings ?
3. 3rd party solutions ?
Any help appreciated, thanks
