PMG as full MX

[Francesco M. Taurino]

hi all,

would it be possible to use PMG as a full MX server for a domain?
say, with external users authenticated via sasl on submission port?
even in this case, we need to modify some postfix configuration files,
enable submission, install dovecot and so on.
and in this scenario, how can we add these "authenticated users" to
the whitelist in the "who objects"?

thanks,

francesco
