Unfortunately, the removal of the footer is a feature not a bug.
In order to be DKIM-compatible and thus help avoid becoming classified
as spammers, we can't mangle message content anymore, just like we
can't mangle the Subject: line.

In principle, the List-Unsubscribe: headers that are now included in
mailing list headers allow MUAs to offer convenient unsubscribe
buttons. Not sure how many of the people who are complaining use
mail agents that don't handle that.
