Thanks Joseph - this is really useful.

By coincidence (whilst researching all of this) last night I cam across
this page:
http://wiki2.dovecot.org/procmail
which says exactly what you suggested. I tried it as an experiment on
just one of my mailing list recipes. It didn't work and dropped through
to my default inbox. This is what I have:

:0 w
* ^List-Id:.*users.lists.fedoraproject.org
| $DELIVER -m $DESTDIR/MLists/Fedora

where:
DELIVER=/usr/libexec/dovecot/deliver
DESTDIR=/home/mark/mail/
are defined in a the main procmailrc

This is what I found in the procmail log:
lda: Fatal: destination user parameter (-d user) not given
procmail: Program failure (64) of "/usr/libexec/dovecot/deliver"
procmail: Couldn't determine implicit lockfile from "spamc"

Why did this mail not get delivered to /home/mark/mail/MLists/Fedora?

Thanks again
