Default Can't send email from new Cento OS 5.5 install

Hi ...

I just set up a new server. It has been colocated and everything is fine but I can't send emails.

Here is what my error log shows:
Aug 11 09:53:04 pcmg sendmail[22632]: o7BGr4FN022632: from=root, size=275, class=0, nrcpts=1, msgid=<20100811165304.GA22595@pcmg.pri>, relay=root@localhost
Aug 11 09:53:36 pcmg postfix/smtpd[22637]: warning: SASL: Connect to private/auth failed: No such file or directory
Aug 11 09:53:36 pcmg postfix/smtpd[22637]: fatal: no SASL authentication mechanisms

Aug 11 09:53:37 pcmg postfix/master[21322]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling
Any help would be great.

Default courier-imap instead of dovecot ... sendmail. Can send but not receive

Sorry that I am do not know very much about email config.

I got rid of dovecot and compiled courier-imap

Now I have courier-imap and sendmail servers on.

Seems to be working fine ... but I can receive mail.

My server is a colocation setup so I really don't know my fully qualified domain name FQDN

I am running a DNS server and I should be able to use jpre.net at my host for receiving mail. I just don't know how to do so.

What is the best way to configure this.

Again ... I can now send email, but my hostname is comming up as "pcmg.pri" which is not even in my hosts file (don't know where that came from).

Yikes ... I really need help.

What's in your main.cf?

Also, make sure that your MX record points to your server. You can check that with
dig mx yourdomain.com
