[Dovecot] Using procmail to mark messages as read in dovecot

[LuKreme]

So, I use procmail extensively, and I have for a long time, but marking messages as 'read' in a Maildir has always been a little wonky:

TRAP='mv "$LASTFOLDER" "${LASTFOLDER}:2,S"'

Since I've switched to dovecot, is there a way to mark a message on delivery as read or not new or seen?
