cannot send mail from one local domain to another

We cannot send mail from one local domain to another. We get a following error:

This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

info@inte.....s.net

Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 13): 550 5.7.1 <info@inte....s.net>... Relaying denied

When trying to restart exim we get [FAILED] on shut down attempt:

/sbin/service exim restart
Shutting down exim: [FAILED]
Shutting down antirelayd: [ OK ]
Shutting down spamd: [ OK ]
Starting exim: [ OK ]
Starting exim-smtps: [ OK ]
Starting antirelayd: [ OK ]
Starting spamd: [ OK ]

And there are too many exim <defunct> processes in memory.

Both domains are present in /etc/localdomains file.

Check for a file in /etc/eximmailtrap , if its there delete it.

I wish it was but it's not.

You need to check the exim error log when sending an email. On Linux it's /var/log/exim_mainlog

Our mistake, sorry. Client has deleted his mail account and forgot about it
