Hi,

Thanks for the reply.
I have already done procedures that you have provided but still Zimbra server sending mails from non existing user/domain without authentication and Origin Host: 127.0.0.1. Please let me know what next I should do to effectively fix this.

Thanks,
Russel

Hello guys,

I've installed Zimbra version 8.7.5 in a CentOS 7 box and I've got the same problem. Has anyone found the solution ?

Thanks.

Roke.

Hi,

You may check zimbraMtaTlsAuthOnly status. It should be set to FALSE.
