[Dovecot] Imap logging and inetd

When I ran /usr/local/sbin/dovecot, the variable 

login_log_format_elements from dovecot.conf was honored. Now when I run /usr/local/libexec/dovecot/imap-login from /etc/inetd.conf, it isn't. How do I get imap-login to write log lines that use login_log_format_elements for the format?

This is dovecot-1.2.alpha3 soon to be alpha4.

Thanks, Jonathan
