Postfix SMTP client auth error

[gugabaga]

Hi,

I have setup a Mail Server - Fedora 7, Postfix, Dovecot.

I want all mails to be routed through my ISP mail server.

I have set
relayhost=mail.isp.com
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password
smtp_sasl_security_options = noanonymous

sasl_password-
mail.isp.com usernameassword

postmap sasl_password

Still my isp is refusing to relay mails.

What am I doing wrong

Try adding:

smtp_cname_overrides_servername = no

Erik.
