| There is an easy way to test if everything is correct, create an email account if you haven’t already and send a test mail to the following recepients, and the results are cut down because the text is too big

| === Logs ===
| |
| You can check the following locations to see if there are errors
| |
| * /var/log/mail.err
| |
| * /var/log/mail.warn
| |
| * /var/log/mail.info
| |
| * /var/log/syslog
| |
| | |
| ; Note
| |
| Make sure you enable testing mode for DKIM if you plan to test, you can also cut down the EXPIRY time so the results propagate faster, so to enable testing mode set the key <tt>'''_domainkey'''</tt> to <tt>'''t=y; o=-'''</tt>
