-
Restore the Mail Enable files from the antivirus quarantine.
-
Copy the content of the following directories from another Plesk server with MailEnable to the production server:
C:Program Files (x86)Mail EnableBin
C:Program Files (x86)Mail EnableBin64
Note: Instructions on files restoration from the quarantine, or adding the directories to exceptions may vary depending on the antivirus used. Please check the documentation of the antivirus for the instructions on how to do that.
