Hi! I have edge server in my production environment .

Some messages are marked as  very high SCL=7 and they are rejected by edge.

Why edge marks messages with so high level. I know that the message from my partners.

Here is part of line from AgentLog

5.7.1 Message rejected as spam by Content Filtering.,SclAtOrAboveRejectThreshold,7

Where can i find more detailed information about how partner messsage receive so high SCL level?

If you wish to turn this off, on your edge transport server type:

set-contentfilterconfig -SCLRejectEnabled $false

The mailbox server can also be instructed to move messages above a certian SCL to the user's junk folder.  That is controlled with:

Set-OrganizationConfig -SclJunkThreshold <some number>
