Comment 4 for bug 386133

It's the "Content Filtering" option. I remember adding "text/html" in the "pass_mime_types" field on the Systers mailing list. The lists on the dev system (ABIWT) do not have this added. We should probably add it to this settings list on the Wiki - http://systers.org/systers-soc/doku.php/new_list_creation_settings. Although, I'm not sure if this has anything to do with the bug in question.

Subject: [Bug 386133] Re: Image/Attachment filtering happens before conversation unsubscribe

Kathy, could you tell me the systers configuration options that cause
the error message? I'm working on this bug and am having trouble
triggering the bounceback message. I've tried sending unsubscribe
messages with images in the signature but the vette error logs indicate
that the messages are being discarded.

Bug description:
A member tried to unsubscribe to a conversation. Because her signature template included an image, her unsubscription request bounced with the following message - "The attached message matched the systers mailing list's content filtering rules and was prevented from being forwarded on to the list membership. You are receiving the only remaining copy of the discarded message."

It seems that filtering out images/attachments happens BEFORE conversation unsubscribe which is not the behavior we expected.
