Hello,
Thanks. The mail is rejected, but it's generating bounce messages,
whereas mail to unknown users that smtpd rejects doesn't get queued at all,
mail addressed to mailman seems to start through the queue rather than be
initially rejected.
Thanks.
Dave.

Because you specify 'example.com' in $virtual_mailbox_domains, its valid
recipients are governed by $virtual_mailbox_maps. The /etc/passwd file does
not come into play. Therefore, if mail...@example.com is not listed in the
aforementioned map, mail addressed to that address is rejected. It seems
everything is working as designed.
