Question
What are limitations for free Plesk Premium Antivirus?
Answer
Premium Antivirus is the default mail antivirus program shipped with Plesk. If an additional license key for Premium Antivirus is not added to the Plesk license key, only 14 mail accounts are protected. It secures random 14 mailboxes in the list of all recipients. There is no permanent list of accounts that are always protected.
The free version of the Plesk Premium Antivirus is designed for test purposes and should be used on a server with no more than 14 mailboxes. In case there are more mail accounts, consider purchasing Premium Antivirus paid license.
