Getting postfix working on debian linux

[s0c0]

I'm running debian etch using postfix as my SMTP server.  I am able to send via my PHP code with the following snippet:

 

function sendMail($to, $from, $subject, $msg)
{
	$headers = 'FROM: '.$from."\r\n";

	mail($to, $subject, $msg, $headers);

	return true;
}

 

But when I try sending from a mail client such as thunderbird or via telnet it does not allow me.  Authentication fails on thunderbird, and in telnet I get the following error:

 

221 2.7.0 Error: I can break rules, too. Goodbye.

Connection closed by foreign host.

 

Here is what my /etc/postfix/main.cf file looks like:

 

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

 

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)

biff = no

 

# appending .domain is the MUA's job.

append_dot_mydomain = no

 

# Uncomment the next line to generate "delayed mail" warnings

#delay_warning_time = 4h

 

myhostname = linux.mydoman.com

mydomain = mydomain.com

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

myorigin = $mydomain

mydestination = $mydomain, localhost, localhost.$mydomain

relayhost =

mynetworks = 127.0.0.0/8

mailbox_command = procmail -a "$EXTENSION"

mailbox_size_limit = 0

recipient_delimiter = +

inet_interfaces = all

 

# Authentication 5-6-07

smtpd_sasl_auth_enable = yes

smtpd_sasl_local_domain = $mydomain

smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated, reject_unauth_destination

smtpd_sasl_security_options = noanonymous

 

There error logs don't give me much to go on either, and yes, this particular server is running on a residential comcast cable connection.

"Authentication fails on thunderbird"

 

Is this with thunderbird on the same linux machine?

 

At a best guess:

221 2.7.0 Error: I can break rules, too. Goodbye.

Connection closed by foreign host.

means that you dont have a FQDN for your server. You need to have a full - client1.mydomain.com
