Nope, I meant that you can define an alternate "user base" that doesn't
rely on your local system users:
table myusers { gilles = 10:100:/home/gilles } # uid:gid:homedir
table vmap { [email protected] = gilles }
accept for domain example.org virtual <vmap> userbase <myusers> [...]
In that example, gilles doesn't have to exist on the system. OpenSMTPD
will assume that a user gilles exists and has uid 10 and gid 100.
Since the myusers replaces the system users lookup, the vmap may refer
to it with everything it implies (wildcards, etc ...)

Yup, that's the way to do it.

Nope, if you want to provide a list of recipients addresses then you
have to provide the mapping.
If you want to accept mail for an entire domain and your MDA takes
care of checking which ones are valid or not, then you can use the
wildcard notation to avoid providing a full mapping:
table vmap { "@example.org" = vmail }
# smtpd accepts [email protected] and uses the "vmail" user
# for deliveries, the MDA can then check if WHATEVER is acceptable
#
accept for domain example.org virtual <vmap> deliver to mda [...]
