Location: Service Configuration/Exim Configuration Editor
What is Exim? According to http://www.exim.org, Exim is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet. It is freely available under the terms of the GNU General Public Licence. In style it is similar to Smail 3, but its facilities are more general. There is a great deal of flexibility in the way mail can be routed, and there are extensive facilities for checking incoming mail. Exim can be installed in place of sendmail, although the configuration of exim is quite different to that of sendmail.
What is the Exim Configuration Editor? The Exim Configuration Editor allows you to modify the behavior of exim by changing certain exim configuration settings. There are two options you have available in the Exim Configuration Editor:
Note: You can edit the exim configuration file by clicking on Switch to Advanced Mode.
1. The Standard Options include the following:
Always set the Sender: header when the sender is changed from the actual sender. (Unchecking this will stop "On behalf of" data in Microsoft(R) Outlook, but may limit your ability to track abuse of the mail system.)
Verify the existence of email senders. - Enables verify = sender/<options>
Use callouts to verify the existence of email senders.- Uses a callout check for the specific mail address.
Discard emails for users who have exceeded their quota instead of keeping them in the queue. System filter file (leave blank to disable) - Sets the filter file used by exim.
2. Click on the check boxes next to each of the standard options based on your personal specifications. A checkmark indicates the option will be turned on.
3. Click on the "Save" button.
4. The page will reload and display the status of your exim configuration settings. You should see a final message at the bottom of the page that looks like the following:
"Your configuration changes have been saved!"
The Advanced Configuration Editor will allow you to modify the default configuration of Exim. Configuration changes made within this editor will be conserved across Exim updates and reinstallation. Changes to the default configuration can significantly impact Exim's performance and may prevent it from operating altogether. Use this editor with caution.
Note: Directly editing the Exim configuration file (usually located at /etc/exim.conf) will only work temporarily as an update to Exim will result in the changes being overwritten.
1. Click on the "Advanced Editor" button to begin using the Advanced Configuration Editor.
2. Each section that you can modify will have a text box (text area) associated with it. Enter/modify the exim file according to you specific needs.
3. When you have finished editing the exim file, click on the "Save" button.
4. The page will reload and display the status of your exim configuration settings. You should see a final message at the bottom of the page that looks like the following:
"Your configuration changes have been saved!"
