bcc is not working

[vagifverdi]

bcc field is ignored and instead is being included into main recipients email headers.

Not sure if the problem is in this library or in mime-mail package. Posted bug there too.

I tested with sendmail functions from mime-mail package, and bcc works correctly. So the problem is in smtp-mail package.

I encountered a similar issue, with cc and bcc failing. Fortunately this package: http://hackage.haskell.org/package/HaskellNet-0.5/docs/Network-HaskellNet-SMTP.html does work as expected, and in my case it was an easy switch to make (see particularly sendMimeMail2).
