How To: Set a Send Delay in Roundcube
=====================================

Roundcube provides an option to limit the number of messages a user may send within a select 
time frame. This setting is in seconds. By default, 
this is set to 0, however system administrators can customize this option with the ``sendmail_delay``
setting in the Roundcube configuration file. 

With the ``sendmail_delay`` option enabled, if a user tries to send more than one message within
the set window, they will receive an error letting them know they need to wait, and for how long:

To Configure the ``sendmail_delay`` Setting
-------------------------------------------

#. Log in to the server at the CLI as root, either via SSH or from the terminal
#. At the CLI, run the following to edit the Roundcube setting template--this will 
   prevent the changes from being overwritten upon update: 

   .. code-block::

      ~iworx/bin/config.pex --customize-template mail/roundcube-config.tpl --for-global

#. Edit the ``sendmail_delay`` setting to reflect the number of seconds that users must wait
   before sending another message. The following example sets a 90 second delay: 

   .. code-block::

      // How many seconds must pass between emails sent by a user
      $config['sendmail_delay'] = 90;

#. Save the file and exit the text editor
