    Nah, you're too young for that. ;-)

    The first one is useful when you want to pass Procmail the
extensions as known to Postfix, instead of parsing them with a recipe.

    The second one turns on explicit delivery, which is probably only
useful if you want to deliver to root. That won't work otherwise,
because when delivering to root, Postfix would invoke Procmail under the
authority of $default_privs (typically "nobody"), so Procmail would be
fooled into delivering the message to "nobody". Of course, Procmail
must be setuid to root to be used that way.

    On a side note, you probably want to drop the "-t" above.

    That's _very_ old, you might consider upgrading to a newer version.

    Not tested:

        for U in /var/spool/mail/*
        do
            formail -I"From " <$U -s /usr/sbin/cyrdeliver -e `basename $U`
        done

(IIRC, Cyrus deliver would bail out if you don't remove the "From_"s).

    Right, $mailbox_transport overrides $mailbox_command, so Procmail
is left out of the game. Well, the solution to this depends on what
you want. If you used Procmail only as a LDA, you can simply forget
about it. If you used it for spam rejection and *simple* filtering,
you might consider switching to Sieve (which comes with Cyrus imapd).
If you used Procmail for more complex filtering, you might want to
leave out $mailbox_transport, and invoke Cyrus deliver from Procmail.
In the latter case, you probably want a fallback for users without a
~/.procmailrc: just create a file

        /etc/procmailrc

owned by root and mode 0600 (IIRC), containing something like

        DEFAULT=|/usr/sbin/cyrdeliver -e $USER

    On a second thought, I think $USER is not available at the time
Procmail reads /etc/procmailrc, so you might try something else:

        mailbox_command = /usr/bin/procmail -a $LOGNAME

and put into /etc/procmailrc something like

        DEFAULT=|/usr/sbin/cyrdeliver -e "$1"

    Cyrus does use some sort of indexed maildir. Knowing that however
doesn't do you any good, since you're not supposed to mess with the
contents of mailboxes directly (bad things will happen if you do).
