Re: Anybody at ATT.net email services?

Our email to att.net has been going through w/o any problems and we
actually have a lot of emails going there.  It may be your IP's are
being flagged as passable for some reason and is causing the resend
action.  This is the first I have heard of they delaying any email like
this though.

You can try [email protected] but I think all that email gets ignored.
