Mailman intentionally removes 'return-receipt-to',
'disposition-notification-to', 'x-confirm-reading-to' and 'x-pmrqc'
headers from list mail. Aside from the fact that these are
non-standard, annoying and unreliable and might return to the list or
the list-bounces address rather than the poster, they could also be
used to fish for membership on a list with a private roster.
If you want to expreiment with not removing them, you need to modify
the code in Mailman/Handlers/Cleanse.py. There's no configuration
setting to do this.
