Question : New PC can not send emails via Postfix with SPF error generated.

Did a Profile transfer to a new PC and now I am getting SPF errors in the mail log on an IMAP Postfix server.
This account is not new the PC is. I can send and receive mail from all other accounts.


Here is the mail log entry-

Feb 24 16:41:29 Mydomaininc postfix/policy-spf[25124]: : Policy action=550 Please see http://www.openspf.org/Why?s=mfrom;id=cmaggio%Mydomaininternational.com;ip=12.34.56.78;r=unknown

Answer : New PC can not send emails via Postfix with SPF error generated.

Sounds like the SPF policy is being broken?
What is it?
