We have an issue where sometimes a person creates a calendar item for an event, and canceling the item causes email to be delivered to the list.
It seems the solution could be looking at MIME header tags indicating it is a meeting invite, and we could block all emails containing: ^Content-Type: text/calendar Placing that in Spam Filter rule does not capture the email, likely because it isn't in the top header section, but within the MIME encoded sections. Does this problem have a known solution? Google didn't find it and I don't see "text/calendar" in my archives of the mailman mailing list. ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
