No, your mailer is not compliant with either the proposed RFC 2821
4.1.1.1, nor with the existing standard RFC 1123 5.2.5.
Your mailer connects from 66.226.235.118, and then gives its name as
mail.efastfunding.com but that name resolves to 66.226.235.114.
The SMTP client "MUST" give its proper canonical hostname in the
HELO/EHLO greeting (or a valid address literal). It "MUST NOT" lie and
give some other name which does not resolve to the address it connects
from.
I.e. either your DNS is wrong, or your mailer's hostname is wrong, or
your mailer is connecting from the wrong address.
You can't pick hostnames out of thin air, and you can't give them
addresses which are not the actual addresses they use.
