vPostMaster doesn't really have, internally, any idea of a "fallthrough"
domain, where messages are delivered to system users rather than the
virtual mailboxes.

It *IS* possible to set up /etc/postfix/main.cf for "mydestination" to
include a domain for direct delivery to a shell user.  For example, adding
"shell.example.com" to the "mydestination", mail for that domain will be
delivered to the system user instead of to vPostMaster.  This does mean
that the mail will not be going through the anti-spam of vPostMaster.

If you want the anti-spam protection, and then messages go to a shell
account, you have to create the account in vPostMaster, and then configure
the account to forward to a domain in mydestination.

SMTP AUTH simply checks the username/password against Dovecot, so
configuring Dovecot to do PAM checking as well as the vPostMaster database
would cause both SMTP AUTH to work as well as POP/IMAP.  vPostMaster
doesn't include that configuration in itself.

How would you expect it to work?  Configure a domain in vPostMaster as
fall-through, and it would then use the system user/password database for
mail delivery for that domain?  Do you expect it to have the anti-spam
features for those users?  If so, I guess those vPostMaster user accounts
would be auto-created on their first login?

Thanks,
Sean
