Aha! On further examination I found a similar example here:
http://wiki2.dovecot.org/Pigeonhole/Sieve/Examples#Plus_Addressed_mail_filtering
I will need to tweak this a bit more, because we want to allow the
user to create a mailbox as s/he wants, whether all CAPS, all
lowercase, or Title Case (as our default setting would create a new
folder if it wasn't found.) But you've surely set me on the right
track here! Thank you!
