Public bug reported: With a mailman list set to apply content filtering, and with the default settings to pass_mime_types of text/html, multipart/mixed and multipart/alternative, mail sent from anyone using the Gmail app on an android device is bounced. The same user can send the same message from the native Mail client on an Android device, or from an Apple device. The problem seems to be that the Gmail app includes a header in the form Content-Type: multipart/mixed; boundary="===============8130305584729002058==" ...with no carriage return after the semi-colon. The only way I've been able to get a list to accept mail from that client app (which is very popular) is to remove pass_mime_types altogether. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1787690 Title: Mailman rejects multipart content from Gmail/android To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1787690/+subscriptions
