Groups (0.8K) Please confirm your request to join dpr-indonesia please figure out which address is doing that and remove it. eg, look at the subscribed log and go backwards in time, sending a test message with headers etc to match a regular list post. Cycle through all the subscribers waiting a minute or two for each and when one triggers the confirm request delete that subscriber. (the test message could say if this genertes crap you will be removed immedately). as for spam I can't say enough about grey listing and ip rbl; I do both of these at smtp level and they are extriemly effective. I also spamassassin at smtp level but I make exceptions for ip of discussion lists, cause I get myself unsubscribed when spam goes to the list and I reject in smtp. For the unfiltered list messages, I use procmail to invoke spamassassin at user level. // George -- George Georgalis, information system scientist <
