Sometimes, and its very very rare, and will never know unless 
reported, a domain has SPF but some reason our winserver.com site will 
reject the mail. Rather then pass the buck, I will simply added an 
WCSAPFILTER.TXT while list ACCEPT IF rule to allow them bypass SPF 
checking.

There is a slight bug with the SPF processor in WCSAP for SPF DOMAINS 
that are using the "exists" macro in their SPF policy.  This is more 
usage for tracking SPF usage, i.e. like tracking that winserver.com is 
inquiring about a domain ABC requiring SPF.   I expect to have this 
mite fix in a small WCSAP update shortly.

If anyone experienced anything related like this, please confirm if 
the domain rejected did indeed have an "Exists" macro in their SPF policy.

Thanks
