Good One !!!!

I think it will be useful to list the steps to change source SMTP IP if exim is the MTA. Here comes the steps

1. Edit /etc/exim.conf with your favorite editor.
2. Locate the section of the file that contains the following:
remote_smtp:
driver = smtp
3. Replace this section with the following modified version :
remote_smtp:
driver = smtp
interface =
4. Restart Exim
