BCC alone is probably the cause of JUNK prefix.
Different spam filtering systems have different ways of working, but one of the rules most of them share is: "If the recipient's email address is not in the TO nor CC, assign HUGE number of spam points."
I wouldn't be surprised of for some systems, this alone would be enough to mark the email as junk.
The way around, apart from the obvious: not using BCC, I'm sorry I'm not much informed about the server-side of things, but these two came to mind:
1) Recipient shall setup a specific rule at their server so that your email address is allowed/white-listed.
2) My webhost offers Email Authentication, and Domain Keys, for my email accounts. I'm not acquainted with them personally, but from what I read both shall improve the chances of emails getting through. For example about Domain Keys they say:
DomainKeys is an e-mail authentication system that allows for incoming mail to be checked against the server it was sent from to verify that the mail has not been modified. This ensures that messages are actually coming from the listed sender and allows abusive messages to be tracked with more ease.
You'd have to check what for options your email service provider offers in that respect.
