We don't have found a way, via GUi ora CLi, to replace the message :
"Following phishing URLs are detected by Fortigate" that FortiOS use in the header of the body of an email when FortiOs report user for a phishing url.
No "config system replacemsg" found for them in cli/config.
Thanks to everyone can help!
Looks hardcoded so if you want to modify this message, maybe you should play with FortiAnalyzer and Automation Stitches...
