Thank you all for your messages. I got an off-list message from a Postmaster of the AOL Anti-spam Division this morning telling me that one of the sets of error messages had been an AOL problem that had been remedied yesterday, that being the last set: RLY:51. He also told me to call the number I had called before and tell them to make a ticket about the URL bounces. Unfortunately, the person I talked to when I called was a Tier 1 person who gave me a case number and referred me to a Tier 2 person. I sent him a copy of one of the messages, and we were going great guns when my cellphone faded. There I was, having to start all over again in the queue, etc. Naturally, I could not get the same person. I was told the request had to come from the Listserv mail administrator. That's as far as we got. I believe the HVU:B1 (URL) situation has been dropped as I have not received any error messages on the URL problem for more than 24 hours. I doubt I have been whitelisted but at least the whole process is clearer to me now. I am afraid the university will not permit me to use the bottom banner if I have to take it to them. It is unfortunate that anyone can block a whole list, even though there are some remedies But for now, it apparently is okay. And I appreciate all of your efforts as well as getting the message from the AOL Postmaster. Barbara Passmore
