We have added domain xyz.com to the system.
the MX record for XYZ.com i mail.xyz.com and mail.xyz.com resolves (after 2 additional CNAME records and the A record of zimbra.abc.com) to our zimbra IP.
When the message is sent to firstname.lastname@example.org it is being delivered to our MTA but gets to the Deffered queue. The error is:
connection to zimbra.abc.com[PUBLIC.IP.AS IN.DNS] :7025 time out.
Why does it want to connect to such address ?
The MTA is on the same server as mailbox store.
