I have a big problem on one of my accounts on a server. When i try to sent a mail (with a internal account on the same server and network.) i get this message back:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

test@psprintersupplies.nl
Unrouteable address

But the strange thing is that i get only on this domain get back this error.

So when i sent a mail to this account with a extern account like @gmail.com there is no problem but when i try to send a e-mail from a account on the same server or network i always get Unrouteable address.

I have try:

/scripts/eximup --force
/scripts/upcp --force

Re-create the hole account and make the e-mail account in cpanel.

check the quota, spamfilters, settings, dns zone.

But when i type this command on shell i see:

command: exim -d+route -bt test@psprintersupplies.nl
