I noticed today that I wasn’t getting any comments. IN fact, I hadn’t received any for a couple of days. When I checked my site however, it wasn’t that I hadn’t received any, but that I hadn’t been notified of them. When I upgraded WordPress to version 2.3.1 recently, I stopped being notified of comments, pingbacks and trackbacks. My e-mail account was still working, and my auto site backup e-mail came in just fine, but those discussion related e-mails didn’t come in. Apparently, this is caused by a change in how WordPress handles these outgoing e-mails. The e-mail account it was trying to send them from was wordpress@(mydomain.com). I don’t have an account by that name, so my hosting service (Bluehost) was justifiably disallowing those e-mails. Adding that account at my hosting service, and the problem is solved.

I’d like to say thanks to Double Blind for showing me how to fix the problem.
