Description

For example, an external spammer wants to impersonate the CEO of a company(ceo@company.com).
The spammer will put 'CEO ABC <ceo@external.com>' in the Email header From, and send such email to a user(victim@company.com).
If FortiMail has been configured with a manual entry 'CEO ABC"/"ceo@company.com' in an impersonation analysis profile to indicate the correct display name/email pair, then such email will be detected by impersonation analysis, because the spammer uses an external email address and an internal user's display name.
