[Exim] SMTP AUTH, Next step ...

I made a mistake while typing my server_prompt (forgot the second semicolon)
so that Outloop Express didn't recognized the prompt, then wasn't sending
login and password.

I corrected it, but now, it seems that exim doesnt recognize login/password
...

Any Idea ?

Here is the log (look at output debug, expanded string = no, at the bottom
of this message):
