The proper resolution would be to contact the administrator of the domain(s) in question and ask them to put in the proper SPF records to allow RIM to send email from their domain.
I think what's happening with them is when a Blackberry message comes in, it hits their spam filtering service who runs spamassassin on it and then relays the message to them, rewriting the headers. Their mail server then gets the message and reads the modified header and processes SPF according to what it sees (the spam box's IP address) which fails since Blackberry specifically denies anyone else sending as them. So they'd have to get Blackberry/RIM to add the spam box's IP to their SPF records, or get the spam box to stop rewriting headers. Or lower their SPF policy (2 may work better for them) - SPF isn't as widely used as everyone wants you to think.
