I think it would be nice if deliver took a -e ${extension} but for now I use 
this in Postfix:

dovecot unix    -       n       n       -       10      pipe
  flags=DORhu user=vuser argv=/usr/local/libexec/dovecot/deliver -d 
${user}@${nexthop}

My sieve scripts, of course, don't know about the extension so I have to 
filter accordingly.
