It appears the netapp configuration for a mail server doesn't lookup MX records (which I guess is used for autosupport). I have two MX records for my mail relay but no A record (by design). Have two A records is not desirable because MTA's will be confused and end up deferring mail for a little bit. I believe with two MX records, they try one then the other. With A records, they only get one back originally, try, defer, then continue to fail that piece of mail until it's re-queued later and happens to hit the other A record. Since dual A records are round robin, there is no real way of assuring it doesn't get the same A record back when it decides to look it up again (and maybe it even caches it for some time, not sure).

Has anyone else experienced this problem?
