That's a successful delivery of a message. The only strange thing that
I see here is that your host first tries to authenticate via CRAM-MD5,
unsuccessfully, and then falls back to AUTH PLAIN. This might happen
when the smarthost doesn't support CRAM-MD5.

We need to see the log of a failed delivery, most probably generateable
by the way Andreas' pointed out to you:

echo foo | exim4 -d some_address@example 2>&1 | tee /tmp/debuglog

and then sending in /tmp/debuglog.

Greetings
Marc
