[tangowebs]

Hi, Im using plesk 7 for windows...
Im not receiving or sending emails from the accounts.

Can anybody help me???

The error is:

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:

[email protected]
unrouteable mail domain "imagendelibres.com.ar"

This is the new error:
MailEnable: Message could not be delivered to some recipients.
The following recipient(s) could not be reached:

[SMTP:[email protected]]: Remote SMTP Server Returned: 550-Verification failed for <[email protected]>

550-unrouteable mail domain "imagendelibres.com.ar"

550 Sender verify failed

Make sure you can resolve imagendelibres.com.ar with your nameservers.

if imagendelibres.com.ar is on your server, make sure its not the hostname, e.g.try changing your hostname to something other than imagendelibres.com.ar
