That would mean you're also blocking _every valid_ e-mail you get by BCC.
The point is a SMTP-Server does not really use To: header fields, when sending
the message to the first SMTP the sender gives 'RCPT TO:' lines before sending
even one header line of the mail.
This 'RCPT TO:' lines are taken into an envelope and given to the next SMTP,
and the next SMTP ... until it reaches the destination.
So your SMTP got told 'RCPT TO:<[EMAIL PROTECTED]>' for this mail and
therefore he tried (and succeeded) to deliver.
