    Hello, we're having a problem where Gmail users cannot send email to accounts on our server that use email forwarders, specifically on accounts with an add-on domain name.

    Example: account domain is example.com and add-on domain is domain.com.

    When a gmail users sends email to susan@domain.com which is a forwarder that is supposed to forward to susan@example.com, gmails bounce back to sender with:
    Code:
    Delivery incomplete
    There was a temporary problem delivering your message to susan@domain.com. Gmail will retry for 46 more hours. You'll be notified if the delivery fails permanently.
    The response was:
    DNS Error: 6996200 DNS type 'mx' lookup of domain.com responded with code SERVFAIL
    
    Please advise, thank you!

    Are you sure the MX records for domain.com are set correctly?

    Have you verified them at something like mxtoolbox.com?

    Yes I checked it out on mxtoolbox and both tests appear ok. I've set this domain up the same as all others in the past and this is the only one exhibiting these issues.

    However when I check it on intodns.com I get the following results with a blue exclamation mark:

    Your MX records that were reported by your nameservers are:

    0 domain.com 18.268.300.428

    [These are all the MX records that I found. If there are some non common MX records at your nameservers you should see them below. ]

    Well, the error message being reported by Google in the message you gave seems to indicate that Google can't find any MX records for the domain name. Perhaps this was a temporary issue or perhaps it's something else.

    What's odd is that I can send email to these forwarders from my gmail account and the emails do get forwared properly. Apparently this only happens with some gmail accounts. :confused:

    Is this not what the MX records should be?

    Gmail's error is pretty clear and if they're unable to do a DNS lookup for the domain's mx records for some reason that would be something that is addressable with Gmail, pending your MX records for both domains are correct (domain.com and example.com)

    The issue may also indicate that your nameservers are not responding to the google resolvers. You might want to check out their threads on the issue here:

    Gmail also has a help forum here:
