Procmail question

I am having a problem with blind carbon copies with my Procmail recipe:

:0
* ^(Cc|To).*user
{
     :0 c
     ! [email protected]

     :0 c
     ! [email protected]
}

For some reason, bcc messages are skipped.  Obviously I can't get the 
bcc header as it is removed by sendmail.

Question I have is, what sort of header do I look for when a bcc message 
comes in because it obviously isn't addressed to the individual with a 
To or a CC header.

I enabled Verbose on the procmail side to track mail, and get better 
Error messages, but it isn't telling me what it is matching against, I 
can't see the mail header so I cannot determine what to match against.

Anyone have any idea?
