    SMTP DNS Resolution


      After change my infrastructure from IronMail to MEG, I have started to be rejected by some domains.


      Those domains said:


      We see the problem with communication between mail servers. When your server (mx for mydomain1.com) tries send email to our server, it presents as mydomain2.com (in helo command).

      Unfortunately mydomain2.com doesn't exist. DNS servers don't resolving this hostname and our server reject this messages. Could you correct name your email server please ?



      Testing my MX Records, I can receive this error message in MXTOOLBOX.COM, any idea of this error message? or what I can I modify in my settings?


      I appreciate a lot of for your help.
