Aldo, we all see that, and it is no less annoying when you work here. But back when Compuserv was the biggy, it seemed like all of my bounces were due to full mailboxes there. And at the end of every (US) college term you get a bunch of "No such user" from the edu sites. Now that AOL is 4 times the size of Compuserv, and 100 times the size of a moderate University, a lot of problems come from there. This is compounded by the fact that AOL (and Compuserv, but they are a lot smaller) are marketed toward a broader segment of society than the other contact points (.edu accounts get checked regularly, be they staff, faculty or students, .com accounts get checked most every business day, etc...) the site may well produce more errors proportional to its size, but I don't know that the difference is significant. The largest of the lists I run is exactly 9% AOL; I've got two AOL users who frequently don't check their mail often enough to keep their mailboxes from filling up, and I've got a couple of compuserv users who do the same thing. (Opps, it appears that now I only have one subscriber from Compuserve. Two years ago the two services were at parity, but 5-6 subscribers. As an aside, a friend, who is postmaster at a large university, told me a few months ago that there is only one site on the network that he can tell is having mail problems simply by the size of his mailbox in the morning. And that's AOL. Vnend
