I am not totally sure, being very new to dovecot, but doesn't dovecot's
"deliver" execute the .dovecot.sieve if the sieve plugin is installed
and configured?

protocol lda {
   # ...
   mail_plugins = cmusieve
}

Seeing when the .dovecot.sievec is created, it looks like that is done 
on delivery time, not when reading.
