SPF record and blackberry

Dear all,

We have SPF record for our outgoing mail server. The problem is when a user sends test mail from blackberry handset to his own company id, mails are going to Junk folder.

I checked the Internet message header in owa. it is showing following message.

X-MS-Exchange-Organization-Antispam-Report: DV:3.3.5705.600;SID:SenderIDStatus SoftFail;OrigIP:178.239.85.10
X-MS-Exchange-Organization-SCL: 6

smtp05.bis7.eu.blackberry.com (178.239.85.10)

do I need to add something to our spf record?

Please help
