I have a hosting account held with justhost, who have been very good up to now, however recently I am seeing some of my emails being rejected by some recipient email systems. I have configured an SPF record via Cpanel, the erorr I receive back is:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

Subject: FW: Example of email

my real email address and domain have been masked with mydomain.net.
Can anybody offer any tests to complete, or guidance?
