If the FortiGate unit recognizes a valid email as spam, there are two methods for changing this behavior.
1). Contact FortiGuard
If FortiGuard anti-spam services are being used, report a false positive for an email address. To report a false positive, go to the FortiGuard AntiSpam web site:
https://www.fortiguard.com/contactus >> Appeal a blocked Spam IP, URL or Email address.
2). Create a local block/allow list.
Create a static block/allow list to have an email address to be checked locally.
First, enable Email-filter:
System - > Feature Visibility - > Email Filter
For 6.2 & 6.4
# config emailfilter bwl
edit 1
set name "default"
config entries
edit 1
set type email
set action clear
set email-pattern "example@example.com"
next
end
next
end
For 7.0
# config emailfilter block-allow-list
edit 1
set name "default"
config entries
edit 1
set type email
set action clear
set email-pattern "example@example.com"
next
end
next
end
Then add the above in the related email filter profile:
# config emailfilter profile
edit "default"
set spam-filtering enable
set options spamfsip spamfssubmit spamfschksum spamfsurl spamhdrcheck spamfsphish
config smtp
set log-all enable
set action discard
set tag-msg "[Spam]"
end
set spam-bwl-table 1 << add the entry created above(for 6.2. and 6.4)
set spam-bal-table 1 << add the entry created above (for 7.0)
next
end
To have the block/allow list take effect enable local check and override SMTP or SMTPS remote check:
# config emailfilter profile
edit "default"
config smtp
set local-override enable
end
next
end
