Most providers provide some kind for forward/reverse mapping, including ATTBI. Often, however, they do provide customized reverse mapping (ie, myhost.mydomain.com). That may be where the disconnect.
I believe that ATTBI has a script that auto-generates forward/reverse mappings on a regular basis. You client may be just in a waiting period before the problem corrects itselft.
