[bug-anubis] anubis as smime proxy

[Johannes.Derek]

Hi,

I am trying to use Anubis as a S/MIME proxy using the suggestions I
found in the archive of this list:
(http://mail.gnu.org/archive/html/bug-anubis/2003-10/msg00001.html)

Unfortunately I always get the following error messages when processing
a mail:

ERROR: In procedure waitpid:
ERROR: No child processes

Here is my .anubisrc:

[...]

---BEGIN GUILE---
guile-load-path-append /usr/local/share/anubis
guile-load-program filter.scm
---END---

---BEGIN RULE---
guile-process full-external-filter /usr/bin/tee /root/tmp.mail
guile-process full-external-filter /usr/bin/openssl smime -sign -in
/root/tmp.mail -signer /root/certtest/elksmime_priv.pem -passin
pass:abcd
---END---

The file /root/tmp.mail is created, but I only get the unmodified
message.
Do you have any idea what's the problem?

Thanks
Johannes
