The problem with closing the list is that it makes things very inconvenient for those who just want to post to ding, but don't want to subscribe. Manual moderation of non-subscribed posters is laborious and results in unnecessary delay for those messages. Something I've proposed to Lars in the past is using TMDA to protect the ding list. The idea is that TMDA intercepts mail sent to ding@gnus.org, and allows the message through if 1) the sender is subscribed, or 2) he is on the "whitelist". Otherwise he confirms his post and is then automatically added to the whitelist so future posts go right through. This is nice because it keeps SPAM off the list while still allowing legitimate non-members to post without much hassle. If you want to see an example of what the confirmation process would look like for non-subscribers, send a message to and follow the instructions you get back. After you confirm that first message, try sending a second, and notice that you don't have to confirm again. > or block the sclp3.sclp.com if possible? You've misinterpreted the mail headers. sclp3.sclp.com hosts gnus.org, so blocking it probably wouldn't be a very good idea. :-) -- (http://tmda.sourceforge.net/)
