I believe the dns load balancing is the most effective due to the nature of cost and simplicity. We have several F5 BigIP 3800 and there really pricy machines , but with there Global Load Balancing service it makes our life easy.

These servers will be in two different cities for maximum redundancy. If I remember correctly, Jake mentioned setting up DNS round robin to balance the two QMT servers. My question is this: Is DNS better for load balancing, or would it be better to utilize a load balancing program like 'balance' (http://www.inlab.de/balance.html) ? Or does it really make a difference for this application. I would be balancing IMAP (993) / SMTP (25) / POP3 (110). Thanks, Scott
