When I first set up exim a long time ago with my isp, I had the same
problem.  The "sender" is your user.  Exim probably sends it as coming from
<username>@sebastian.  The SMTP server of  onu doesn't like that.

Solution: use address rewriting to change <username@sebastian> to the email
address you want people to see.

In my exim.conf, at the bottom under "Address Rewriting":

*@carrera      pat7@gmx.net    Ffsr
^                        ^     ^ 
|                        |     rewrite it in these fields(From sender reply-to)
anything from my machine |
                         |rewrite it to this

Hope you understand my ascii art :)
