<DIV><FONT face=Arial size=2><SPAN class=021053110-19062006>I'm using dovecot 
& postfix to bring smtp auth to our customers. Normal mail clients have no 
problem at all and I'm so satisfied.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=021053110-19062006>However, we're 
having problems with Microsoft Exchange server clients. We're using our 
postfix-dovecot server as smarhost for several Exchange Servers, and we wish to 
use TLS + basic authentication for these outgoing mails.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=021053110-19062006>But it seems that 
the way Exchange talks to our server, dovecot gets confused, and password is 
used instead username for user lookups, so authentication 
fails.</SPAN></FONT></DIV>
