You can't configure Mailman to just do it without making code changes,
but there are possibilities:

To place the burden on john, he can subscribe both addresses and set
john at example.com to nomail.

To place the burden on you, assuming you have access to Mailman's
command line tools, you could periodically (via cron) run a script to
list the members, find those with '+' in the local part and add the
address without the +... in the local part to the list's
accept_these_nonmembers. There is a script at
<https://www.msapiro.net/scripts/non_members> (mirrored at
<https://fog.ccsf.edu/~msapiro/scripts/non_members>) that can do the
adding to accept_these_nonmembers.
