You need formail -s.
formail -s spamassassin -d < old > new
Yup.
Exhibit A (Spamassassin):
% time formail -s spamassassin -d < spam-100-msgs.mbox > spam-100-clean.mbox
User=75.360 System=4.680 Wall=1:21.88 (U+S)/W=97.7%
Exhibit B (Procmail/sed):
% time formail -s procmail ~/remove_sa_markup.rc < spam-100-msgs.mbox >
spam-100-clean.mbox
User=0.660 System=0.330 Wall=0:01.09 (U+S)/W=90.8%
That's about 75x faster for procmail.
