Specifying channel authorization levels

To control authorization on a particular channel, use the auth keyword to set an authorization level on the MCHN line in the /usr/mmdf/mmdftailor file.

MMDF provides seven levels of authorization:

free

Performs no authorization checks (default). Any channel that you do not set authorization for is set to free.

inlog

Logs incoming authorized and unauthorized access, but allows mail to pass.

outlog

Logs outgoing authorized and unauthorized access, but allows mail to pass.

inwarn

Logs incoming unauthorized access, transfers the message, and sends a warning to the originator.

outwarn

Logs outgoing unauthorized access, transfers the message, and sends a warning to the originator.

inblock

Logs the incoming unauthorized access attempt and bounces the mail.

outblock

Logs the outgoing unauthorized access attempt and bounces the mail.

Example format:

   MCHN auth=inblock
