why does qmail eat my From headers?

[uckelman]

Does anyone know why qmail would replace the From: field in my outgoing mail 
(which should be "From: Joel Uckelman <[EMAIL PROTECTED]>") with just my 
email address? Is there some way I can stop qmail from doing this?

(NB: as far as I can tell, it is qmail's fault, as it happens when I inject a 
message directly as well as through my MUA).
