I assume you've seen the vette log entry saying the message was discarded, but it doesn't say why. Essentially all discards are because the message met some condition for which the action is Discard. These are all in the list's web admin interface. The most common one is Content filtering with a filter_action of discard and a message whose top level Content-Type: is either in filter_mime_types or not in pass_mime_types. This could be, e.g., a multipart/related message with multipart/alternative and multipart/mixed as the only multipart types in pass_mime_types or a text/html message without text/html in pass_mime_types. It is a common misconception that convert_html_to_plaintext will handle the latter, but you have to accept the HTML before you can convert it. Other places to look for Discard actions are: Privacy options... Sender filters member_moderation_action dmarc_moderation_action (Mailman 2.1.18 and up) discard_these_nonmembers generic_nonmember_action Spam filters header_filter_rules If you want to see the reason and the message, change the action from Discard to Hold. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
