One of your (Microsoft's) servers' HELO string is misconfigured...

    Question

  • I have a customer who can't receive email from your service because one of your servers is misconfigured. That server is using a host in its HELO/EHLO string that does not exist or has no A record (TX2EHSOBE009.bigfish.com). It would benefit you to configure your servers correctly.

    Just a heads up...
