simply put NO
if the mail is forwarded (sent by you) to the receiver
it cannot possibly pass the original senders spf policy (as he did not list your ip in his policy
this is why a receiver of forwarded mail needs to whitelist those ips that forward email to him from all spf checks.
(if the receivers isp offers him no method of doing this, then he needs to pick a better isp or consider getting the forwarder to use SRS capable software, or just use pop3 instead of forwarding)
(unless as often stated the forwarder changes the address the mail comes from to be one of his own (and thus within his own spf policy) with a method such as SRS)

Also note that I am running Amavisd-new as a frontend in order to do some spam filtering before forwarding. I think this is the problem, but want to verify that in fact this should pass SPF checks. I'm suspecting that the parasun.com is not looking far enough back in the headers, therefore the failure. Or, am I all wet and this should in fact not pass?
