Had this myself, until yesterday. I suspect your wrapper is running under UID
majordom, rather than daemon (or root). I also suspect that your sendmail.cf
does not have 'majordom' as a trusted user, so the '-f' flag on the sendmail
calls is being ignored.
Add the 'T' definition below to your sendmail.cf - it worked for me.
Precisely the symptom I saw.
