Message Certification
Enable certification of inbound messages
Click this checkbox to enable certification of inbound messages. When MDaemon receives an inbound message needing certification, it will query the trusted CSP to confirm whether or not the message should actually be considered "certified." If so then the message will either be exempt from spam filtering or have its Spam Filter score adjusted, depending up which option you have selected below.
Host name(s) of certification services that I trust (space separated list):
Use this box to enter the host names of the certification services that you trust. If you trust multiple services then separate each one with a space.
Don't apply spam filter to certified messages
Choose this option if you wish to exempt certified messages from the Spam Filter.
Certified messages add this many points to the spam filter score
If you do not wish to exempt certified messages from spam filtering, use this option to designate the amount by which you wish to adjust the message's Spam Filter score. Ordinarily this should be a negative number so that certified messages will receive a beneficial adjustment. The default setting is "-3.0".
