delivery from local users

Hi,

I'm running a chroot'ed Postfix on a SuSE 9.1 machine and
everything is very fine and fast.

My only problem:
If my system wants to send a message e.g. for a failed cron-job or
something else this message gets stuck in the queue and can't get
delivered to my internal server where all mailboxes are.

My mailboy has an alias to receive this mails, so this shouldn't be the
thing.

Could this be because I'm running postfix chroot'ed ?

If you want some .conf files, tell which you want.

Kind regards,

Paul
