DomainKeys and SPF Record Checking
April 10th, 2010You probably know that you can configure DomainKeys and SPF records in cPanel >> Email Authentication (if you didn’t, there you go 
). If you’d like to confirm that your TXT records are working properly, here are some resources for you:
SPF Record Check – via HTTP
PoliteMail’s SPF Check – outputs a brief breakdown of your records details – the IP addresses permitted in the record, the hostname, and the mailserver name. Then outputs the TXT record it queried.
MXToolBox’s SuperTool – Provides SPF checks, among other useful queries.
SPF Record Check – via email
This is pretty neat – you can send an email to spf-test@openspf.org from the domain you want to test, and it will reject the message, but in that rejection message, you’ll see the results of your test:
spf-test@openspf.org
SMTP error from remote mail server after RCPT TO:
host mailout02.controlledmail.com [72.81.252.18]:
550 5.7.1
SPF Tests: Mail-From Result="pass": Mail From="test@cpaneladmins.com" HELO name="server.cpaneladmins.com" HELO Result="none" Remote IP="12.34.56.78"

OpenSPF.org’s Wizard – If you want to configure SPF records manually, go here. Note that you won’t be able to edit the records via cPanel >> Email Authentication later on, though.
