Unsupported configurations

In some situations, the MMDF Configuration Manager may build an incorrect or incomplete MMDF configuration for your site. Use the MMDF administration managers to update the configuration after running the MMDF Configuration Manager if you:

• Use more than one communications channel to exchange mail with a particular host.

  The MMDF Configuration Manager sets up MMDF to communicate with the other host using the first configured channel in this order:

  1. TCP/IP

  2. UUCP

  3. Micnet

  If your host accesses another host using two or more channels, but you do not want to use the first applicable channel to transfer mail, the MMDF Configuration Manager does not configure MMDF correctly. See ``Channel tables''.

• Have a host that does not exchange mail with every host on each configured channel.

  The MMDF Configuration Manager sets up MMDF to exchange mail with every host on the configured channels. For information on removing hosts from a configured channel, see ``Managing mail hosts''. When configuring UUCP and Micnet, you have the opportunity to remove hosts with which you do not exchange mail.

• Exchange mail with two hosts and want to prevent one host from passing mail to the other host through the local host.

  The MMDF Configuration Manager sets up MMDF to allow one host to send mail through the local host to the other host. To prevent this, you must set up authorization to prevent the transfer. For information on how to do this, see ``Specifying MMDF authorizations''.

• Have more than one channel of the same type.

  The MMDF Configuration Manager lists all the hosts that your host accesses using a particular communications protocol in the same channel. To set up authorization to restrict a host's access on a channel, see ``Specifying MMDF authorizations''.
