Restrict Users from Sending or Receiving Email

This article applies to recent versions of SmarterMail. View articles for SmarterMail 15.x and earlier.

By modifying the service access settings, domain and system administrators can restrict user accounts from sending or receiving email in SmarterMail. For example, if a company wants to use SmarterMail for internal communications, the system administrator can set up the service access settings to only allow users to send email to other users on the domain by disabling that user's Outgoing SMTP and Incoming SMTP. Note that doing so will prevent users from utilizing mail clients, so removing access to syncing protocols (MAPI/EWS, EAS, IMAP and POP) should be considered as well.

Configuring Service Access Settings
By default, domain administrators have the ability to limit user access to POP, IMAP,  incoming and outgoing SMTP, webmail and XMPP/Group Chat. (Though Group Chat is an Enterprise-only feature.)

Limiting Access for a Specific User 
Follow these steps to configure the service access settings for a specific user:

  1. Log in as the domain administrator.
  2. Click on the Domain Settings icon.
  3. Click Accounts in the navigation pane. Then be sure the Users tab is selected.
  4. Select the user you wish to edit.
  5. Find the Service Access card.
  6. All options are enabled by default. Toggle off the appropriate service to disable access to it.
  7. Click Save.

Limiting Access for All Users on a Domain
Follow these steps to configure the service access settings for all of the users on a domain:

  1. Log in as the system administrator.
  2. Click the Manage icon.
  3. Click on the Actions (...) button.
  4. From the dropdown menu, select User Defaults.
  5. Find the Service Access card and uncheck the appropriate checkboxes to disable service access.
  6. Click Save.
  7. Click the Propagate button.
  8. Scroll to the Service Access area and select the appropriate checkboxes to identify which settings to propagate.
  9. Select where to propagate the new settings: to all domains or to specific domains. If pushing to specific domains, add them to the Domain line. 
  10. Click Propagate.
  11. The changed settings, limiting service access, will propagate to all users of the domain(s) entered.
