Hey everyone,
I did a yum install postfix from the centosplus repository to get postfix with database support.

When I try "/sbin/service postfix start", I'm getting the following in /var/log/maillog:

postfix/sendmail[10132]: fatal: file /etc/postfix/main.cf: parameter mail_owner: unknown user name value: postfix myhostname = mail.exchango.com mydomain = exchango.com myorigin = localdomain inet_interfaces = all mydestination = exchango.localdomain, localhost.localdomain, localhost, localdomain

postfix[10147]: fatal: file /etc/postfix/main.cf: parameter mail_owner: unknown user name value: postfix myhostname = mail.exchango.com mydomain = exchango.com myorigin = localdomain inet_interfaces = all mydestination = exchango.localdomain, localhost.localdomain, localhost, localdomain

I checked my /etc/passwd and /etc/group for the postfix user and postfix, postdrop user groups and they're all in there. I'm not sure what I need to do to start up postfix, as I tried this on my home machine (Centos 5.4) and didn't run into these issues.

Thanks!

I don't know if there was some funky syntax error or typo, but I copied my main.cf from the box that worked and it's working now.
