I dunno if there is a BCP covering smtp submission/relay server load balancing/fail over. I'd make an educated guess that just about everyone with more than one submission/relay server is using round robin DNS. > If there isn't a nice howto already, I guess I can figure this out myself - There are many.

My point was that you've already paid for support. Simply call and ask RHEL support the question you're asking here. Surely they'd point you in the right direction. > Would just like to hear the lists opinion before going in any specific > direction, and figuring out that was the wrong one...:) ! This question doesn't come up very often. When it does the OP is working at scale (think dozens of relays) and he's after parallel performance optimization, not simple fail over redundancy. The extremely low frequency of this question should tell you something about the solution people are using, and the level of difficulty required to implement it. I.e. this requirement is mundane, has been around forever, as has the solution, which is round robin DNS. -- Stan
