It will still work if your incoming MTA recognizes addresses of the form

   listname-confirm+xxxxxxxxxxxxxxxxxxxxxxxx at example.com

as an address to be delivered to listname-confirm at example.com.

The confirmation message the user receives is From: an address like the
one above. Simply replying to that message (i.e.sending the reply to
listname-confirm+xxxxxxxxxxxxxxxxxxxxxxxx at example.com) will work if
the MTA delivers it to mailman properly.

In Postfix, you need

recipient_delimiter = +

for this to work. VERP should not affect this as it manipulates the
envelope sender, not the From: header.
