Have had Zimbra in production for almost a week and a half now, and the users are loving it! Have had a few DNS issues to sort out, but all are fixed now except this one problem, which is troubling me.
Any mail addressed to a user at hotmail.com or msn.com gets deferred. The error is:
host or domain name not found. name service error for name=hotmail.com type=mx: host not found, try again.
a 'dig mx hotmail.com' or 'dig mx msn.com' run on the Zimbra server result in a timeout, even though I know my servers are looking everything else up ok.
I know this may have something to do with reverse lookups, can anyone assist me?
