permission denied on dovecot-sieve.log?

Getting a fair number of these:

temporary failure. Command output: Can't open log file /var/log/dovecot-sieve.log: Permission denied

I saw an earlier thread saying to chmod that file to 666, but that won't help after the next logrotation, since it creates the new file 600 again   It looks like this:

/var/log/dovecot.log
/var/log/dovecot-sieve.log
/var/log/dovecot-lmtp.log {
    compress
    weekly
    rotate 10
    create 0600 vmail vmail
...

I think you need to give dovecot/sieve.log its own stanza with 666, no?
