Issue Plesk Email Security

[AndyWe]

Server operating system version

Ubuntu 22.04.2

Plesk version and microupdate number

18.0.52#3

Until now, I used the free version of "Plesk Email Security". Therefore, I couldn't enable the email scan for some mailboxes - or so I thought. Now that I've purchased it, I'm still being notified that enabling the virus scan for incoming and outgoing mails is not possible because my license allows only a limited number of mailboxes.

However, I can't find this 'number' anywhere. Does anyone have a solution?

Thx
