Sure it does! For about a year now. It even supports IETF headers!
What you need is to get in touch with your system administrator,
and tell him to change his LOCAL SYSVARS to have BSMTP = 1
keyword. Then you'll get BSMTP mail jobs, and your server will
perform much better too. (R.Listserv users, plz ignore this message,
