[Exim] TLS & OE

Hello,

Has anybody dealth with MS Outlook Express support TLS?
I'm keep getting:

set_process_info: 76544 handling incoming connection from x.xx.ru [a.b.c.d]
host in host_reject? no (option unset)
host in host_reject_recipients? no (option unset)
host in auth_hosts? no (option unset)
host in auth_over_tls_hosts? no (option unset)
host in tls_hosts? no (option unset)
host in sender_unqualified_hosts? no (option unset)
host in receiver_unqualified_hosts? no (option unset)
host in helo_verify? no (option unset)
host in helo_accept_junk_hosts? no (option unset)
SMTP>> 220 y.yy.net ESMTP Exim 3.33 #2 Mon, 22 Oct 2001 10:30:02 -0400
set_process_info: 76544 handling incoming connection from x.xx.ru [a.b.c.d]
ready for new message
smtp_setup_msg entered
SMTP<< L
SMTP>> 500 Unrecognized command
SMTP>> 421 y.yy.net lost input connection
...

at exim debug (no EHLO even)
and OE error:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'y.yy.net', Server: 'y.yy.net', Protocol: SMTP, Port: 26, Secure(SSL): Yes, Error Number: 0x800CCC0F

I've tried OE-5.5 also with the same negative results, but everything is alright
with Outlook 2002.

Internet Options->Advanced->Security->TLS-1.0 is turned on
What could be problem?

Thank you in advance.
