    This isn't a question about being able to send mail to gmail, it's a question about mail being rejected by gmail and the reason they're doing that is because of the highlighted text - they think you're a spammer. Read the details on the help page that google has provied in their link - this isn't a Zimbra problem.

    Hi ,

    there is two option 1 for dedicated server and 2 for relay server.

    if you have dedicated server then you have to setup DKIM in zimbra mail server. ( File Attached )

    and if it is relay server then you have to configure DKIM at your hosted location.
