Block Users

 

  • The 'Block Users' area lets you block outgoing mail that is routed through Secure Email Gateway. You can block individual users or entire domains.
  • The interface lets you view existing blocks, add new block rules, and search users by name and domain.
  • Click 'SMTP' > 'SMTP-AUTH' > 'Block Users' to open the interface.  



    The interface allow administrators to:
    • Add blocked users
    • Blocking Lifetime 
    • Remove users from the blocked list
    • Search for blocked users
    • Export list of blocked users
    • Import list of blocked users from a file


    Add a Blocked User


    Type the username (or part of the username) of the user you wish to block in the 'Username' field. You can then set how the rule should be applied using the drop-down menu:
    • Starts With – Blocks users whose names begin with the entered text
    • Equals To – Blocks users whose names exactly match the entered text
    • Contains – Blocks users whose names contain the entered text somewhere in their name. Will also block exact matches

     



    • Click the 'Add' button to apply your choice. The item will be added to the list with the category type displaying on the left side.



    Blocking Lifetime


    The 'Blocking lifetime' refers to the number of hours the email address will remain blocked at the SMTP Server. The available intervals are 'Unlimited', '1 hour', '6 hours', '12 hours' and '24 hours'.

    • Click 'OK' to confirm the deletion of all blocked users.

    Search for blocked users

    • Click the 'Search' link at the top of the interface



    • In the search field, enter a full or partial name and click 'Search'. 
    The items that contain the entered search text will be displayed.




    • To display all the items again, click 'Clear'. 
    • To remove the search field, click the 'Search' link again. 


    Export blocked users to file

    • Click the 'Export' link at the bottom of the screen



    • Download the blocked user list as a text file to your system.
