[Dovecot] Dovecot 2.0.7 (8793036f6de8) seems to miss some defaults for vsz_limit

Latest Mercurial seems to miss defaults for some services e.g. 'managesieve' and 'lmtp'. Example error message upon start:

dovecotdoveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(managesieve-login): vsz_limit is too low failed!
