dovecot - Feb 2009 - sendmail smtp auth using client socket

Hi list

I searched the net, but could not find something related.

Is it possible to export the client socket to sendmail for smtp auth?  
What would be the sendmail.mc configuration for this?

    #client {
       # The client socket is generally safe to export to everyone. Typical use
       # is to export it to your SMTP server so it can do SMTP AUTH lookups
       # using it.
       #path = /var/spool/postfix/private/auth
       #mode = 0660
       #user = postfix
       #group = postfix
     #}

It can also be the other way round: can Dovecot use Cyrus SASL for  
user authentication?

I need to use sendmail, ip based solutions like pop-before-smtp or  
poprelay are not an option.

Thanks, Mike

Not currently. They speak different protocols. Would be nice to have
that feature some day, but I'm not planning to write support for it
anytime soon.

No.

Through pam, if you set "MECH=pam" in sasl config.

Have you considered using "LDAP based" authentication in dovecot and
sendmail?
