[exim] exim in vserver issue

Hello!

I've issue vith exim running on vserver - http://linux-vserver.org/
I've two vservers running an the same host server.
But then I send message from one vserver to anover, I've got an
error:

2005-08-19 07:38:57 lowest numbered MX record points to local host:
example.com (while verifying <denis@???> from host example2.com
(example2.com) [192.168.26.24])

Looks like exim from one vserver knows that exim on other vserver is on
the same host.
All e-mails from/to Internet goes fine.

Any ideas ?
