Each instance has its own mail queue and scheduler. If an instance
needs to receive mail via SMTP, THEN it needs its own IP address
or TCP port.
To submit mail with the Postfix sendmail command:
/usr/sbin/sendmail -C config-directory-of-alternate-instance ...
Begin quote from Postfix sendmail manpage
-C config_file
-C config_dir
The path name of the Postfix main.cf file, or of its parent
directory. This information is ignored with Postfix versions
before 2.3.
With all Postfix versions, you can specify a directory pathname
with the MAIL_CONFIG environment variable to override the loca-
tion of configuration files.
End quote from Postfix sendmail manpage
