I get emails occasionally from people, stating that they are emailing me, and are annoyed that I am not reply. The problem is that I am replying, but their ISP sucks (for lack of a more professional term).
Hi,could you please tell me why my account became inactive (I had to re-register today). Thanks.
I sent a reply, and received this:
----- The following addresses had permanent fatal errors -----
(reason: 550 (name_withheld_by_admin)@earthlink.net...User unknown)
I encourage everyone who thinks they are having email problems to talk to their ISP (internet service provider). Your problem might be bigger than you think.
