Greg, thanks for trying to interpret what I was saying. I've never
used Postfix before and I wasn't using some of the terminology
correctly.

I think I've finally read enough postfix documentation, including most
of _Postfix, The Definitive Guide_, to ask this question correctly.

If the mail server's hostname is mail.mycompany.com, then a typical
Posfix install has:
mydomain = mycompany.com
myhostname = mail.mycompany.com
mydestination = $myhostname, localhost.$mydomain, $mydomain
and so any mail someone@mycompany.com would be delivered using the
local delivery transport. In other words, "someone" would have to
be a UNIX account on the system.

The Postfix rule is: domains listed in mydestination are local
delivery, and domains belong to exactly one address class.

However, most of my mail recipients will never have a UNIX account
on mail.mycompany.com. I guess I could use re-write rules to change
those users to another domain which is a virtual domain, but I don't
want another domain name.

Since I want virtual delivery (or preferably mixed virtual/local),
I can't list $mydomain or $myhostname in mydestination. So, I
assume that mydestination would either be null:
mydestination =
(which would not allow any local delivery) or just localhost:
mydestination = localhost
(which would allow local delivery for mail sent to
someone@localhost).

Then I guess I'd want $mydomain and $myhostname as virtual domains:
virtual_mailbox_domains = $myhostnam, $mydomain
and I'd get virtual delivery. If I needed to get local delivery
for a few accounts (like root), I'd need a rewrite rule to change
mail sent to root@mail.mycompany.com -> root@localhost
(assuming that mydestination = localhost).

So will this work? Can I list $myhostname and $mydomain as
virtual_mailbox_domains instead of in mydestination? Will
mydestination = locahost
allow re-write rules for certain users for local delivery?

That's what I was trying to get at by asking how to get
virtual (or mixed virtual/local) for the canonical hostname.

I'm about to start experimenting with Postfix to try this all
for myself. I eventually want to set up Postfix + OpenLDAP +
Dovecot or Cyrus IMAP + Cyrus SASL + SquirrelMAil

Thanks again.
