How to allow or disallow alias account to login to the webmail, IMAP, etc?


  • Execute the below command on the respective mailbox server to check the current status first. It will show TRUE or FALSE.
 zmlocalconfig alias_login_enabled
  • Execute the below command to disallow login to alias account, for security reasons, this is the recommended setting.
 zmlocalconfig -e alias_login_enabled=false 
  • Execute the below command to allow login to alias account
 zmlocalconfig -e alias_login_enabled=true 
  • Once done with the above changes make sure to restart the mailbox services.
 zmmailboxdctl restart
