Is this the correct IP?

[vaio1]

No it is only a sample ip but what is the problem?
what is the main troubleshoot in these cases?

[vaio1]

Found in these forum:

Code:

smtp_sasl_auth_enable = yes

Code:

smtpd_sasl_auth_enable = yes

The omission of the letter 'd' there has made my life very difficult, but that's the answer to the fatal error in the log file.

Now the emails are sent by the server but now I have received this message by email:

<admispconfig@localhost.localdomain.mywebsite.net>: mail for localhost.localdomain.mywebsite.net loops back to myself

thanks

[falko]

Please add
localhost.localdomain.mywebsite.net
at the end of /etc/postfix/local-host-names and restart Postfix.
