Hi, My mail server host name is mail.domain1.com, Created two domains in this standalone zimbra server like domain1.com and domain2.com. When send mail from domain1.com, didn't get any error. mail delivered successfully.

But I am trying to send mail from domain2.com, getting below undelivered mail returned to sender error. any solution for this?

This is the mail system at host mail.domain1.com.

Have you read the information in the link that google has provided you in that message? You should read it and follow their advice or some further diagnostics on the status of your mail server reputation and/or whether you are on any blacklists.

There is no blacklist in zimbra. But i read the details from link. advised to get ISP smtp relay.

My comment was about whether your mail server was on any blacklists (RBl).

I could send mail to other mail id. google only rejected. I trusted my domain in google postmaster.

mta host name(mail.domain1.com) is mismatch compare with sender domain name(domain2.com)

I do exactly the same thing and NO smtp servers refuse my mail and that includes google.

BTW, that is the way all mail servers work otherwise they wouldn't be able to host multiple domains that were different to the domain used for the SMTP response. ;)

You can't set a 'hostname' for each domain you host, the server has a primary domain and the hostname is set to reflect that and should have a valid reverse DNS - you can then send mail for however many domains you host on that server.

Yes, the solution is given in the message that you received from google and on the error page to which they directed you - use a relay server.
