    Exclamation Receive and Send Mail problems with dns lookups in admin?

    Ok here is my problem. When I start up zimbra everything starts up just fine and No errors.

    If I have the check box Enable DNS lookups in the admin panel under MTA tab checked I can send mail internally and externally but I don't receive any mail to users mailboxes. It stays in the Mail Queues. Now if I uncheck the Enable DNS lookups in the MTA tab I can receive mail in the mailboxes but I cant send mail externally only internal.

    Anyone help on what I am missing here and need to change?

    Thanks Nick

    You need to have correct DNS A & MX records set for the domain you're using. If your DNS is OK then you probably need a split-DNS setout that outlined here.

    My current setup is I have my domain at godaddy.com with the A & MX record pointing to my zimbra server at home. I have all the mail ports and necessary ports open in my firewall box which is in front of my zimbra server. There is no way setting up the split-DNS then? Could I somehow point my mta through my local internet providers dns or some other way. Just curious because I was running postfix, courier-imap, and webmail before without doing this and everything worked fine for sending and receiving.

    Thanks Nick

    If you're positive that your DNS is OK then you'll need a split-DNS - IMO, it's far better doing that. You could relay through your ISPs server but then you are dependent on their server working all the time. It's your choice really, either way will work.
