: Did you try the unsubscribe addresses listed at : http://lucene.apache.org/solr/mailing_lists.html
Furthermore, every Solr email contains the following headers, which modern email clients should expose to you for "email list management" ... List-Help: <mailto:[EMAIL PROTECTED]> List-Unsubscribe: <mailto:[EMAIL PROTECTED]> List-Post: <mailto:solr-user@lucene.apache.org> List-Id: <solr-user.lucene.apache.org> ...if you are having trouble unsubscribing, you should contact the List-Help address, you should *not* send (two) mass emails to every on on the list. Lastly: unsubscribing causes the mailing list software used by apache (ezmlm) to immediately send a reply asking you to verify that you want to ubsubscribe (to prevent other people from unsubscribing you without your knowledge). I just performed a test and verified that ezmlm replied to my unsubscribe request within a matter of seconds. If you have not seen any replies like this to your unsubscribe requests, please check any "junk mail" or "spam" folders you may have ... at least one person i know had that problem with Exchange/Outlook. -Hoss
