See http://technet.microsoft.com/en-gb/library/aa996295.aspx for an introduction to Exchange's handling of Sender Policy Framework (SPF).

SPF allows a DNS domain to include a record which indicates which servers are authorised to send e-mail from that domain.  In your case, Exchange is telling you that the SPF record does not exist in DNS, which is pretty common.

Depending on how you've configured Sender-ID filtering, this may quarantine the message or do nothing.  It is likely that there are other causes for the message being quarantined.
