Definately agree... My MX's do all of my mail scanning. They are several ways to keep them in sync. I keep all my configs in a mysql database on my mailstore that is replicated to my MX's, I'm sure everyone has their preferred method of doing this. I chose my setup, because I do lots of mysql development. Someone mentioned the backup MX being out of sync... They don't have to be in perfect sync, a backup MX could have a bayes databases a day or two behind, or not be accepting mail for a few new customer and it would not bother me a bit, but a backup MX handling bounces or queing up tens of thousands of emails to hammer my mailstores(or in your case primaryMX) when they come back online, and using my resources to assist a spammer or DOS an innocent bystander is unacceptable. -- Darrel O'Pry Systems Administrator Thing.net Communications, LLC -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
