Yes. I think you are asking for a means for the superior list to selectively ignore those bounce messages. Either that, or to intercept the subscription disabling process so that the address is not disabled. A more pertinent question would be be why is the superior list should/would be seeing those bounce messages. My thoughts exactly. Occasionally I have had bounce messages sent by other servers back to some address other than the address in the Return-Path: header - some have gone back to the list, some to the list-owner, etc. IOW, something screwy in one of the thousands of servers I send mail to.

I have heard that, in contravention of RFC 2821, some MTA may do this but see my comments below. If the messages your script chooses to pass down to the subordinate list are simply posted by it to the subordinate list then any bounce from the subordinate list's subscribers should be received by and handled by the subordinate list's bounce processing; and MM doesn't normally tell posters about bounces resulting from distribution of their posts by the list. Are you certain that the bounce messages do not actually stem from occasional failure of your script to take successful delivery of a message from the superior list? So how is your script, having had the message from the superior lists delivered to it by your MTA, sending the message to the subordinate list. Are you using SMTP from your script or are you using the $prefix/bin/inject script or something else? If you are using SMTP (or inject'ing into the default incoming queue) then by the time MM has received the message from the MTA and then processed the message through the subordinate list: 1. the envelope From should be the subordinate.listname-bounces alias 2. the Sender: header should be subordinate.listname alias 3. the Error-to: header should be subordinate.listname-bounces alias 4. The envelope To and To: header should be that of the subordinate list subscriber 5. The From: header should be that of the poster to the superior list, superior.listname alias, the subordinate.listname alias or some other explicit address depending on the settings of the reply_goes_to_list and reply_to_address attributes of the superior and subordinate lists. This being so it is difficult to see (even with an not-quite-RFC-conformant-MTA along the way) how a bounce message in respect of a message coming from the subordinate list is finding its way back to the superior list, with the subordinate list identified as the address to which the message was sent. I grep'd the logs on my server, and couldn't find any entries for the proxy address that didn't have status=sent on the line. ___/ / __/ / / Ed Leafe http://leafe.com/ http://opentech.leafe.com -- Richard Barrett http://www.openinfo.co.uk -- Mailman-Users mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ This message was sent to: [EMAIL PROTECTED] Unsubscribe or change your options at http://mail.python.org/mailman/options/mailman-users/archive%40jab.org

Do you have the 'bounce_notify_owner_on_removal' attribute on for the superior list, If you can tolerate that it should give you visibility of any bounce that triggers the suppression of your subordinate list's address on the superior list. You can get at the headers etc on the messages that are bouncing and maybe a hint as to what is going wrong. ___/ / __/ / / Ed Leafe http://leafe.com/ http://opentech.leafe.com -- Richard Barrett http://www.openinfo.co.uk -- Mailman-Users mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ This message was sent to: [EMAIL PROTECTED] Unsubscribe or change your options at http://mail.python.org/mailman/options/mailman-users/archive%40jab.org

When the list sends the message out, it supplies its own Return-Path:, etc., headers, as any list would do. But what is going to happen if your script decides _not_ to forward the message to the mailman wrapper. Would you not be better using os.popen() if you decide to deliver the message to the subordinate list. As things stand is not the normal post script is being asked to read a message from an empty pipe? It may cope with that but why make it do so and what are the consequences. A little sleight-of-hand: if the message is not to be sent to the list, I add a particular header to the message. The subordinate list is then configured to automatically discard any message containing that header. So all messages get forwarded to the list, but only the good ones ever get sent out to subscribers. ___/ / __/ / / Ed Leafe http://leafe.com/ http://opentech.leafe.com -- Mailman-Users mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ This message was sent to: [EMAIL PROTECTED] Unsubscribe or change your options at http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
