Undelivered Mail Returned to Sender - just occur to mydomain.com
My version is Zimbra 7.2.0_GA_2669
I can send e-mail using Zimbra web mail to all domain, include mydomain.com, but when use a client, example Mozilla Thunderbird,
I get this error ( Undelivered Mail Returned to Sender ) .
But any other domain I can send mail, just can't send
