bind & sendmail both as non-root

["Krzysztof Mazurczyk" <kmazurczyk@wskiz.poznan.pl>]

Hi there,

I use potato r0. On my system bind (8.2.2) and sendmail (8.9.3-23) are
running together.
Bind run as non-root daemon, sendmail is running by inetd. When sendmail is
run as root is OK. When I chown sendmail to mail:mail and tell inetd to run
as mail then sendmail writes to log
    ... reject=451 ... Sender domain must resolve

The question is: Is it possible to have bind and sendmail both as non-root
processes on the same Linux box? And how if any.

Thanks
