procmail recipe wanted: clearsigned -> detached signed mail

[Christoph Hertel]

Hi,

a while ago (a year or so, maybe even on another ML, I'd be sorry for
that :), in one of those clearsigned vs. detached/MIME-signed e-mail
discussions, I read about a procmail recipe that rewrote a clearsigned
e-mail in a MIME-message with a detached signature. At the time, I
did not have the possibility to use procmail, but now..

Did I just dream of this, or is there really something like it? Can
somebody point me somewhere?


Thanks,

Christoph
