Said script:

    #!/bin/sh
    #
    # /usr/local/sbin/deliver.sh
    #
    # A wrapper for running spamassassin & Cyrus deliver
    #

    if [ "$#" -ne 2 ]; then exit 64; fi

    user="$1"
    extension="$2"

    if grep -q "^$user:" /etc/passwd; then :; else exit 67; fi

What does the above line do?

    /usr/local/bin/spamassassin -F0 -P -x \
       -p "/home/${user}/.spamassassin/user_prefs" |
    /usr/local/cyrus/bin/deliver -e -m "${extension}" "${user}"

Since '-P' is now the default, that's no problem.  What did '-F0' do?

I'm beginning to think that procmail may not be very good for use with
Cyrus.  I'd originally "locked" on it because it seemed like an easy way to
pipe the mail through commands (such as spamc), but if I'm going to script
that anyway, then I don't such much need to keep it.

Thansk for the pointer!  It may not be *exactly* what I needed, but I think
it's close enough that I should be able to go on from here.

Do you have a good reference for that?  I Googled "sieve cyrus" and got more
information than I could handle.
