dovecot - Apr 2011 - Running mailfront under dovecot2.x service supervision

Hello,

I'm trying to run mailfront SMTP (http://untroubled.org/mailfront/) under
Dovecot 2.x process/service supervision

My intention was to utilize the fact that dovecot2.x seems to have some kind
of generic process/service supervision as well as builtin ssl support.
But I cannot get the most simple generic service setup (without ssl) to
work.  

Currently running dovecot 2.0.11 on FreeBSD 8.1


service smtp-auth {
        executable = /usr/local/bin/smtpfront-qmail
        inet_listener smtp-auth {
                port = 587
                ssl = no
        }
}

I have added the above to dovecot.conf

Once I start dovecot everything seems fine - no errors in the log
But at the first attempt to telnet to localhost port 587 - I instantly get
the indication of never ending forks in the dovecot log (see below) -
neither do I get the SMTP prompt that I expected in my telnet session - it
just hangs.

Apr 19 10:05:34 smtp-auth: Error: mailfront[43539]: bytes in: 0 bytes out:
29
Apr 19 10:05:34 smtp-auth: Error: mailfront[43541]: bytes in: 0 bytes out:
29
Apr 19 10:05:34 smtp-auth: Error: mailfront[43543]: bytes in: 0 bytes out:
29
Apr 19 10:05:34 smtp-auth: Error: mailfront[43545]: bytes in: 0 bytes out:
29

Question is if I've misconfigured something or if it is impossible to
utilize dovecot2.x this way ?

PS: Now I know that I could use daemontools or such for this task - but I
like the dovecot ssl handling and would like to end up by wrapping this smtp
service inside same dovecot ssl that I use for IMAPS.

Any feedback is more than welcome - I'm stuck

Thanks in advance Uffe

Correct dovecot is not an smtp server.
My goal is what I wrote in the initial email - but I try to explain in other
words.

Dovecot2.0.x has the ability to setup somewhat generic supervised services
ala daemontools services if you know that tool.
Dovecot uses these services internally to wrap an ordinary imap session into
an ssl session.
And that is exactly what I would like to do with my mailfront session - wrap
it into a ssl session using the generic service setup present in dovecot
2.0.x

As far as I can see - the services that you define inside dovecot.conf does
not have to relate to imap at all and since smtp and imap go hand in hand in
order to have a fully working email setup - then why not have dovecot
control all the services ?

The services have to be written explicitly for Dovecot, using Dovecot's
lib-master library.

Is smtpfront-qmail trying to use inetd-style execution? Maybe Dovecot
could some day support that, but it's not really in my near future
plans.

Also the service is supposed to do the SSL itself internally, so you
really can't do any of this.
