From another Experts-Exchange thread:
Type their domain in to this tool (an SPF record checker) and see if it passes.

If not, the problem is on their end. Tell them to fix their SPF record. An invalid SPF record means it could be spam / or a forged address and it seems reasonable to me to reject such messages?

A real time saver, for complex SPF setups.
