In 1801f (version 7.4.7 )Email is configure, how we test it 

[funkylicious]

check https://community.fortinet.com/t5/FortiGate/Technical-Tip-How-to-configure-alert-email-settings/ta-p...

To collect the debug outputs for email alerts:
diagnose debug reset
diagnose debug enable
diagnose debug console timestamp enable
diagnose debug application alertmail -1

Send a test activation email: 
diagnose log alertmail test

Disable the debugging afterward:
diagnose debug disable
diagnose debug reset

Not working, I try but its not forward the test email.

the debug logs should show you from the perspective of the FGT what's happening.

if the logs show that everything is ok, i would move with the checks on the SMTP server side if anything arrives/goes.
