[Exim] inetd and root user problem

HI!

I'm running exim 3.34 from inetd on root user. When i change user to mail,
exim do not check rela hosts of incomming connections.

On root user:
HELO test.domain.com
250 mydomain Hello real.connected.hostname [real IP]

on mail user
HELO test.domain.com
250 mydomain Hello test.domain.com

why?
