As a follow-up to the Sender header discussion back on 2006-04/05...
On 2006-06-17, we disabled Sender header rewriting at our site, using the attached patch.
Since then, we've received no complaints whatsoever from our users about bounces not being caught, and the complaints about recipients using Outlook seeing "bounce" addresses have ceased.
Based on our experiences, I'd strongly recommend that this patch be applied to the official Mailman distribution.
Regards, James
