 Receiving Mails Problems dns lookups
I've been attemtping to get zimbra opensource beta 2 working on a Red Hat enterprise rel 4 update2 that is installed in a DMZ. The dmz interface has a non routable address and the firewall has all of the appropriate ports open including 25 and 7025. When I turn dns lookups on in the server admin mta window I'm able to send mail to wherever I want, but I cannot receive mail. Turning the dns lookups off allows me to receive mail but not send it. The hosts table has the localhost.localdomain set at 127.0.0.1 and mail.xxxxx.org is set to 172.xxx.xxx.xxx. The external routable address is only set in dns. The zimbra.log indicates a failure of lmtp when dns is on and no failure when it is off.
We need some direction as to how to set zimbra to handle this.
