I don't think you should have to (or want to) name the A records the same - that's what the equally weighted MX is for - but I also don't think that is necessarily your problem if you are getting the expected results when running nslookup from the Barracuda.

The Barracuda's forward mail to a smarthost, and since they're clustered, I can't specify separate smart hosts per device. Barracuda documentation indicates this is accomplished using MX records. I created an MX record named testmx.domain.com<http://testmx.domain.com> and two A records both named test.domain.com<http://test.domain.com>, one for each of the downstream smart hosts. However, both of the barracuda's appear to favor only one of the smart hosts when delivering outgoing mail. Repeated NSLookups against the MX record seem to alternate between the A records as expected. Any ideas on why this wouldn't work? - Sean --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe exchangelist
