I had the same problem. I believe the root cause was that there is a
forward(5) for root that redirects all mails to my regular user. Adding
an alias for root seems to confuse smtpd if there is already a .forward
file. My solution was to create an alias for my regular user. The chain
is now:
root -> user -> u...@example.net
