[exim] Can I make messages destinated to local user/domain g…

Hello,

I'm using exim4 on a dedicated server (by Online.net). I use the
smarthost configuration to make all mails be sent by the SMTP server of
my DNS/email provider (Gandi). It works only for adresses != of the
servers domain.

'echo "foo" | mail bar@???' works
'echo "foo" | mail ork@???' doesn't

Can you please give me a hint?
Thank you.

Regards.
