That looks, as it has already been said, that your client is directly
starting the SSL negotiation, which is inappropriate for connections
to the server's port 25/TCP.

Debian's exim doesn't advertise SMTP AUTH over unencrypted
connections. And since your serverf doesn't advertise STARTTLS, it
looks like you didn't enable TLS, probably by not having read the
chapter "Using TLS" in README.Debian.gz.

Not knowing this is probably a sure sign of not having read the
copious amount of Debian specific documentation.

If it would help for Kmail, that would have been documented. Actually,
Kmail is pretty good in protocol compliance and doesn't need any hand
holding to work.
Please note that this hack is only needed for Outlook _Express_ _4_,
and not for any later version of Outlook Express, nor for any version
of Outlook (without Express) that I am aware of.

If you used any Debian exim4 package before, then the failure is a
surprise to me. If you used exim 3 before, then please note that you
didn't do an upgrade, but you installed an entirely different package.
There is a chapter "Updating from exim 3" in README.Debian.gz, and the
very first sentence in that README file says that exim4 is an entirely
different package which does not offer a smooth upgrade path from exim
3.

People running a mail server are widely expected to know their
protocols and basic debugging techniques.
