No problems here with the two lists I run, although I'm not a stranger to problems with blocklists or list users inadvertently reporting list messages as spam. This is almost certainly not going to have anything to do with Mailman, but more to do with the reputation of the IP address of your virtual server at Linode or IP netblock ("neighborhood") you are sending from. If you Google around for the error you reported, you should be able to find a form to request de-listing. Perhaps they will while-list your server's IP address even if they are not thrilled with the overall experience with emails from Linode address space. -- Best regards, Robert Braver rbra...@ohww.norman.ok.us ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
