Occasionally as a server owner you will need to suspend the ability for individual accounts to send mail. This can be due to an email sending spam and damaging your server's reputation, or any number of other potential reasons.
Inside of the 'Email Accounts' interface in the appropriate user's cPanel account, you can select 'Manage' on a given email account to edit restrictions on the account:

Once you have selected the appropriate restriction, select 'Update Email Settings' at the bottom of the page and all settings will be saved.
When you wish to remove these restrictions you'll navigate to the same page and simply change the setting back to 'Allow'.
