Earthlink Issues

    Question

  • I have a user trying to send an email to a user at EarthLink. It is being rejected with the following message.

    xxx.xxx.xxx.xxx rejected your message to the following email addresses:
    xxxxx@xxxxx.net (xxxxx@xxxx.net)

    A problem occurred while delivering this message to this email address. Try sending this message again. If the problem continues, please contact your helpdesk.

    mx-mastin.atl.sa.earthlink.net gave this error:
    ERROR: No or mismatched reverse DNS (PTR) entries for xx.xx.xx.xx.

    I have confirmed that the FQDN in my send connector matches the PTR record for my IP.  EarthLink did not even want to talk with me. 

    Thanks in advance!

    Terry

  • If you're sure that your PTR record is right, then EarthLink has the problem and there isn't much you can do about it.

  • When I look at the header returned from EarthLink it doesn't reference my IP or domain, but it does when I send to my personal email:

    Diagnostic information for administrators:

    Generating server: Exchange2013.abc.local

    ray88padgett@earthlink.net
    mx-jacana.atl.sa.earthlink.net
    Remote Server returned '550 ERROR: No or mismatched reverse DNS (PTR) entries for xx.xx.xx.xx'

    Original message headers:

    But when I send to my personal address the header contains what matches the PTR

  • What is the value of the FQDN property on your send connector?   It should be morrowinsurance.com since that's what your PTR record says.

  • Agree with Ed, run below command to check the FQDN setting of outbound send connector:
    Get-SendConnector | FL Identity,FQDN,AddressSpace

    Please remove sensitive information (including server name, domain name, IP address, organization name and etc) from your reply, it's very important and imperative.

  • Allen,

    I ran the command and FQDN shows as xxxxxxx.com

    I have to be missing something, but I don't know where.  The only place I'm getting issues is with earthlink and mindspring.

    Thank,

    Terry Robinson

  • Hi Terry,

    Sorry for later response because of my vacation.

    Since this issue only occurs on Earthlink and Mindspring, also PTR record is correct, we highly recommend to contact its provider (submit your request with PTR record check).

    Best Regards,
    Allen Wang
