Subject: Secondary Mail Server Activity

Since setting up a second SIMS box to act as a backup mail server, I've been seeing the occasional activity in the log indicating that it is indeed receiving some mail that is then passed on to the higher-priority mail server. Is this normal?

I had expected that it would only see activity when the higher-priority server was down. Does this perhaps indicate that my primary SIMS box is unresponsive?

At what point does a MTA give up on the high-priority server and begin looking for the lower-priority boxes? Could the RBL lookups be taking too long and making the primary SIMS box look unresponsive?
