Managing mail with MMDF

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
