Greetings! This is the mlmmj program managing the <linux-man@xxxxxxxxxxxxxxx> mailing list. Your mail host rejected some of the messages we tried to deliver. This usually happens if we have accepted a spam message, but your mail server refused to take it from us (because it's spam). This automated probe is just a test to make sure that there are no other problems with mail delivery to your account. No action is required on your part -- if you are seeing this message, that means everything is normal. (In fact, you can add "Subject: Bounce probe" to your filters to avoid seeing this message in the future.) For internal tracking purposes, here is the list of bounced messages: - 1685
