[Exim] problem with "mail pboucher@robotel.ca" from mail ser…

Greetings,

My Exim 4.05 mail server is working great.
I have this problem. When sending Email from the Mail server itself
using the Mail command I get
theses Error:

- SYSERR(root): MX list for robotel.ca points back to mail.robotel.ca:
No such file or directory

I also have:
- Mail loops back to me (MX problem?)

I am trying to find the cause of this problem, and sometimes i have the
error
Mail sendmail[11881] forward /home/pboucher/.forward.mail: group
writable.

I use RedHat 7.2 with exim 4.05 that i have upgraded from 3.35.

Everything else is working fine.. I am just out of options.. I tryed the
qualified_hostname option
No effect..

Any idee?
