Customization screen) and the anti-spam feature (in the Anti-Spam General

Type

address or an MIME header. 
Select IP to have the device check e-mail for a specific source IP address.

Select E-Mail to have the device check e-mail for a specific source e-mail address 
or domain name.
You can create a whitelist entry for your company’s domain name (or e-mail

employees.
Select MIME Header to have the device check e-mail for specific MIME headers or 
values. 
Configure blacklist MIME header entries to check for e-mail from bulk mail

configure whitelist MIME header entries to allow certain MIME headers or values 
that identify the e-mail as being from a trusted source. 
Select Subject to have the device check e-mail for specific content in the subject 
line.
