Protocols and actions

In an email filtering profile, there are sections for SMTP, POP3, and IMAP protocols. In each section, you can set an action to either discard, tag, or pass the log for that protocol.

Protocol	Available action
SMTP	Pass: Allow spam email to pass through.
	Tag: Tag spam email with configured text in the subject or header.
	Discard: Discards (blocks) spam email.
POP3 & IMAP	Pass: Allow spam email to pass through.
	Tag: Tag spam email with configured text in the subject or header.
MAPI:	Pass: Allow spam email to pass through.
	Discard: Discards (blocks) spam email.

For example, to tag spam SMTP email, use the following commands:

config emailfilter profile
    edit "smtpFilter"
        set spam-filtering enable
        set options <options>
        ...
        config smtp
            set log enable
            set action tag
        end
    next
end

MAPI email filtering

MAPI is a proprietary protocol from Microsoft. It uses HTTPS to encapsulate email requests and responses between Microsoft Outlook clients and Microsoft Exchange servers. The configuration of MAPI email filters are only possible through the CLI.

To configure the MAPI email filter in the CLI:

config emailfilter profile
    edit "myMapiFilter"
        set spam-filtering enable
        set options spamfsip spamfssubmit spamfsurl spamfsphish
        config mapi
            set log enable
            set action "discard or pass"
        end
    next
end
