Sendmail Email Unable to send... do not know where to change this

[Pascal Miquet]

Did you try to send manually an Email to vance ?
If sendmail if setted correctly, vance should receive your email.
To solve my problem, I've added the smtp to the /etc/hosts file.
In my case the smtp isn't the provider one but our Mail server.

You may also have a look to the webmin interface, to manager your
server, and services attached to it, like sendmail.
