Scalix send the mail but the the mail isn't delivered

[tpatricio]

Hi,

I have installed the scalix on a CentOS x86_64.
I have made all the configuration and I'm able to receive mails on the sclalix mailboxes.
When I'm try to send a mail by the scalix webmail interface the mail is set as sent but never arrives and I never receive a error mail.
Some one can tell me what is the probles and how to fix it?

Thanks

When I send a mail for another scalix mailbox the mail is delivery but isn't when is for another server.
I have made the sendmail configuration by the script that is on the scalix folders.
