This is bug with ID PPPM-5467 which is planned to be fixed in future Plesk updates.


  1. Create additional administrator account in SmarterMail.
  2. Set created account credentials in Plesk ( Tools & Settings > Server Components > SmarterMail Server ).
  3. Change primary administrator's account password in SmarterMail.
  4. Set primary administrator's account credentials in Plesk (optional step).
  5. Remove additional administrator's account in SmarterMail (optional step).

If there were too many failed attempts to log in with the incorrect credentials, following steps are required to increase login attempts:

  1. Open the C:\Program Files (x86)\SmarterTools\SmarterMail\MRS\web.config file .
  2. Edit the value number to reflect the number of failed attempts the user can make before the block will be implemented:
    <add key="ForgotPassword.BruteForceDetection.TriesBeforeBlock" value="10"/>
