    hi,
    one of clients is reporting a strange problem that we have no idea how to fix. we've recently moved server to a cpanel-based one. client has set up two domains - lets call it domainA.com and domainB.com on the new server but only domainA.com has had its DNS entry pointed to the current server (not domainB.com) problem is when client tries to email himself to domainA.com using his domainB.com email address, he gets the following error:

    when client tries to email us from this particular domain (domainB.com) - the mail will bounce (with same error) as well. this does not happen when he tries to email domainA.com from any other mail services (such as hotmail, his own isp email account) any idea how we can fix this problem?

    many thanks.

    We could possibly help you troubleshoot this if you gave us real domains, we can't do anything with domainB.com :)

    I'm showing your mailserver is set to mail.teksys.com.au, however this is a CNAME. You can't have CNAMEs in MX records, they need to be A records instead, make mail.teksys.com.au an A record, and it should work :)

    Shows you have more problems than just MX records.

    Somebody needs to properly setup the DNS records.


    Mailservers should NOT send to mail.teksys.com.au.

    Have to disagree with that as 'mail.domain.com' is the norm for most MX setups. In this case though, the IP address found '216.17.107.230' is incorrect, which is probably why that msg. showed.

    Actual IP address for teksys.com.au. is 65.75.145.201.
