All IETF mailing list seem to now require this &%!$# confirmation procedure. This particular message was rather ironic; I was sending a request to "postmaster@xxxxxxxx"! Who decided to implement this filtering, and why did they do such a poor job of it? Whose -----Original Message----- From: ietf-action@xxxxxxxx [mailto:ietf-action@xxxxxxxx] Sent: Thursday, December 24, 2009 1:20 PM To: Christian Huitema Subject: Confirm: ietf-action@xxxxxxxx:phQqLmSzPbBA:BttiZVJDKqxGAJxkqjzyRLPoJnA_T9FrS9ksVw Confirmation of list posting -- confirmation ID: phQqLmSzPbBA The ietf.org mailing-list server has received a list posting from huitema@xxxxxxxxxxxxx to ietf-action@xxxxxxxx with the subject 'Why am I receieving this message?' As the sender address isn't subscribed to the list, and has not been confirmed earlier, we have to request a confirmation of the address. To confirm the address, send a message to ietf-action@xxxxxxxx, with the same subject line as this message. (Simply sending a 'reply' to this message should work from most email interfaces, since that usually leaves the subject line in the right form. The reply's additional "Re:" is ok.) If you do not wish your posting to the list to go through, simply disregard this message.
