Personal Quarantine Report not working

Hello,

 

I'm trying to implement personal quarantine on my FortiMail VM (6.0.4).

After following the Admin Guide, I can't send report to the user manually and the scheduling is not working too.

 

The log message when I'm trying to send report to an user:

 

ColumnContent#507Date2019-04-12Time14:22:02.264SubtypesmtpMessageSpamreport: spam report is disabled for User: xxxxLevelinformationLog ID0003009808TypeeventActionNONEUIspamreportUserxxxx

 

And for the scheduling report :

 

ColumnContent#23592Date2019-04-11Time17:00:00.273SubtypesmtpMessageSpamreport: skips anti-spam profile spamreport disabled user path /home/xxx/info~xxxxLevelinformationLog ID0003001925TypeeventActionNONEUIspamreportUserspamreport

 

I use IP policy only and the FortiMail is in Gateway mode and I think, the quarantine report is actived everywhere (Security -> Quarantine Report, Setting, Control ; Profile -> Antispam, Action ; Domain & User -> User -> Receive spam report).

 

Thanks for your help !
