postconf fatal error

[DocHoof]

I am following the guideline for, "The Perfect Server-Fedora 9". I have made it as far as step 12, "Now we configure SMTP-AUTH and TLS:"
It tells me to type:
postconf -e 'smtpd sasl local domain='

and I get:
postconf: fatal: missing '=' after attribute name: "smtpd sasl local domain="

Any ideas?

Figured it out. There is a mistype in the tutorial; an underscore should follow each as in 'smtpd_sasl_local_domain'.
