Hum.

I wonder how different spam filters would handle a BCC: header that was
blank. - I may have to try this.

I'm betting that it would be better (from the the point of view of the
mis-configured / mis-programmed filters) to have the sender be the only
recipient in the To: header. Even if the To: header was like this:

To: "Friends of Sender" <sender(a)domain.tld>
