Barbara! Sounds like AOL turned on you after it left the listserv at StJohns alone for while. You see two errors. One claims that the message contains spammish URLs. As it is a 5xx series error, I find it unlikely your list members actually received these messages. The other is a 24hour-long block. All e-mail from your listserv node (based on the IP-address) will be blocked during that period. AOL thinks listserv is a spam relay for two reasons: - lazy folks who don't bother to look up how to unsubscribe use the 'this is junk' button in the AOL e-mail software. - list owners, who receive spam via the -request@ address, report valid spam as junk getting your host in trouble. The first you can solve by: - requesting AOLs Feedback-Loop - changing the headers of the lists that appear in the reports to use Auto-Delete=Yes,...,Probe(1). - Then, once every other day you have the opportunity to recognize the junking list member in the Return-Path header. It's a slow route that takes weeks to take effect, and the flow of such reports won't ever stop. I place folks on NOMAIL automatically upon receiving an abuse report of a probed message. The script e-mails them a kind explanation. Of those less than 10% goes back to 'mail' status, 25% junks your kind note, and the remainder is presumably glad that their subscription 'disappeared'. For the 2nd, the list owners: - You could teach them to use the limited filters available in AOL and then not to use the junk-feature in the folder that -request@ mail is delivered to. Note that most spam won't have the -request@ address in the To-field. - or, what I ended up doing, is relaying all e-mail to AOL based owners through SpamAssassin. Which is an administrative pain, but was in the end the only thing that resolved the semi-regular blocks. White-listing may also help. The feedback-loop and white-listing request form are available at http://postmaster.info.aol.com/ If you read the small print of the white-listing, you make yourself contentually responsible for all mail you deliver. No postmaster of a mailing list host is likely going to commit to something like that. After a month, we got white-listed without that clause. I spent a -lot- of time on this since October. Before you dive into this, you want to consider if a single provider is worth dozens of hours of your time. Ultimately you're one-sidely responding to continuing fires, basically doing their postmaster work for them. Oh, one more thing. The AOL members are going to hear from their ISP that you/the postmaster needs to contact them. Reality is, only the AOL member has a contract and is the only person who will (eventually/hopefully) be listened to. Encourage your members to persevere through the 3-4 levels of standard answers the AI-bot will fire off. > Let me say, they are making up for lost time. I'll be short: Good luck. Jasper
