Mudcat has helped me many times, and here I am again. I have several email accounts, and recently I tried sending myself a note from one to the other, but it vanished. Many times. Tried turning off spam filters, turning off McAfee email screening, tried everything I could think of, including spending an hour on the phone with AT&T tech support. His conclusion: a fluke.

Well, the fluke is back to stay, apparently and I can't figure out what is causing this. I used to be able to do this. Last time it got all "fluked" up the address had turned up as a blocked address on my web server. No blocked addresses are there now. The message goes into my sent folder but never appears in the inbox or spam or anywhere else at all. Just vanishes. Except for after 59 minutes with tech support, when it showed up once and then never again after we both hung up.

Any ideas?
