Hi all, I just maked $SUBJECT to run. The main problem was, that in Dovecot are by default enabled only plain digest-md5 and cram-md5 authentication mechanisms. While MS Outlook knows only "LOGIN" mechanism. So, Outlook users wasn't able to use SMTP AUTH.

The solution is to change a line in dovecot.conf:

mechanisms = plain digest-md5 cram-md5 to: mechanisms = plain digest-md5 cram-md5 login

I suggest Timo to change the default configuration, and the page

http://wiki.dovecot.org/Authentication

-- more precisely the line

"LOGIN: Similiar to PLAIN, not very useful. [in 1.0-tests only]"

-- I think, that this line is a little confusing. Becouse since one can use Dovecot for SASL authentication, "LOGIN" is starting to be useful (because of the M*S* bullshit).
