I forgot to include the mailing list in a reply to Stephen and I wantied to follow up here in case what I learned is helpful to others.
One of the things Stephen suggested was that postfix was filtering the headers. That was true in my case. The configuration code I inherited had the following lines in /etc/postfix/header_checks /^List-Unsubscribe:/ IGNORE /^List-Subscribe:/ IGNORE > How are you capturing mail at postfix? For capturing the email at postifx I used the following steps I found on another website to defer SMTP sending so I could look at emails while they were "in process" by postfix. postconf -e defer_transports=smtp; postfix reload # send the email to the server mailq # Use ID from mailq to examine the email using postcat postcat -vq C23D82B60024 # Re-enable SMTP sending postconf -e defer_transports=; postfix reload; postfix flush As for the question about debugging in rfc-2369.py, I did have additional log.debug calls in the "process" method, but was not seeing anything from them. Perhaps they were not getting called as Stephen suggested. Stephen also mentioned in a private email to me about RFC 8058 "One-Click Leave" which is intended to make it easier for folks to unsubscribe from lists. We don't have an implementation in Mailman 3 yet, but it looks like a reasonable protocol (ie, not that easy to abuse, though not impossible). It can probably be implemented in Postfix (but it might not be straightforward). https://datatracker.ietf.org/doc/html/rfc8058 ________________________________ The contents of this e-mail, including attachments, are intended for use by the named addressee only and may contain information that is confidential or private according to applicable law.
