FortiMail 200E didnt send Quarantine E-Mail Reports

Hello,

i have a problem with my FortiMail 200E. I updated the firmware from 5.6 to 6.0.1.

After the update the users didnt receive any quarantine reports. Before they receive quarantine reports.

I checked settings, but cant find any misconfiguration.

I use for antiSpam Profile with AS_Inbound -> Default Action : UserQuarantine_Inbound -> Final action: Personal quarantine

Has anyone an idee ????

Thanks a lot
