Spam- Report missing

I do not get any spam reports.
Using the commandline

• pmgreport -debug 1
  works, I also get daily usage reports
• pmgqm status
  lists all users and # of spam in quarantine
• pmgqm send -debug 1
  empty output

Do you have any hints, where to look for?

Version Mail Gateway 7.0-7
LXC installation on Virtual Environment 6.4-13
Kernel Linux pm-mailgw 5.4.41-1-pve #1 SMP PVE

Thanks,
Birger
