Set Maximum Recipients per Email Message

A system administrator may want to limit the amount of recipients per email to prevent a user from overloading the spool of the mail server. The maximum number of recipients is calculated across all fields: To:, Cc: and Bcc: In addition, Max Recipients can be set for all domains using Domain Defaults or managed on a domain-by-domain basis, as needed.

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

To configure the maximum number of recipients per email as a Domain Default, do the following:

  1. Click the Manage icon.
  2. Click the Actions (...) button. 
  3. From the dropdown menu, select Domain Defaults.
  4. On the Limits card, find Recipients per Message. Type in a number to correspond to the maximum number of recipients a user can add to an outgoing message If you don't want to limit the number of recipients, type in 0.
  5. Click the Save button.
  6. Once you've modified this setting, you will want to propagate the change to all domains on the server.
  7. To do this, click the Propagation button.
  8. A modal window will open, where you can select the setting(s) you want to propagate. 
  9. Once finished making your selection(s), click the Propagate button.
     
To modify settings for a single domain:
 
  1. Select the desired domain from the list of domains in the content pane.
  2. The domain's settings will open.
  3. Find the Limits card.
  4. In the Recipients per Message field, type in a number to correspond to the maximum number of recipients a user on that domain can add to an outgoing message If you don't want to limit the number of recipients, type in 0.
  5. Click Save.
