If you mean the email sent to the potential subscriber asking her/him
to confirm the subscription, the answer is no. See below for more
discussion.

Look in Mailman's 'bounce' log.

Here's what happens with the above settings.

A bounce is returned to list-bounces. If it is not recognizable, it is
forwarded to the list owner (bounce_unrecognized_goes_to_list_owner:
Yes). If it is recognized, the bouncing address is determined. If this
address is not a list member, the bounce is ignored and nothing
further happens with this bounce. If the address is a list member, the
bounce is scored and logged in the bounce log. If it is the second or
subsequent bounce in the same day, it is logged only. If the score
reaches the threshold, the member's delivery is disabled and the owner
is notified (bounce_notify_owner_on_disable: Yes). The owner notice
contains a copy of the bounce DSN. This is the only time the owner
sees an actual DSN. A warning is also sent to the bouncing user.

After this point, processing is by cron/disabled which looks at members
with delivery disabled by bounce and sends additional warnings (at 7
day intervals) and ultimately removes the member if still disabled by
bounce after 21 days.

If a subscription confirmation request bounces, and the DSN is
recognized, it is ignored because the bouncing address is not yet a
list member.
