During last weekend I encountered some extremely strange email-related behavior, and I'm wondering if it could be caused by some kind of network security hole. It seems that when I sent email to addresses at aol.com via my ISP, it simply dropped into a black hole. I got no rejection message of any kind; the only way I even knew there was a problem was that people at AOL told me they hadn't received mail that I verified I had sent to them. I was able to narrow the problem slightly by sending mail to fictitious AOL addresses like zzxqdec26a@aol.com, which would normally produce a ``no such user'' return message. I didn't get such a message. The truly strange thing is that I could send mail to all my normal destinations other than AOL and it was received properly. Furthermore, I could send mail to AOL addresses from my Yahoo and Netscape accounts and it was received properly. It was as though there was a black hole somewhere on the path between my ISP and AOL that swallowed the email but didn't affect other paths. Whatever the problem, I did not encounter it today so I can no longer experiment with it. Does anyone here have ideas as to what the problem might have been? This behavior is not just unlike any I've ever seen before; it's unlike any I've even heard of before.
