[you86]

Hello everyone

I used below tutorial to configure mail server
http://www.howtoforge.com/isp-mailse...ysql-centos5.0

everything went fine.. but now the problem is when i try to send email using outlook, connection to smtp server timed out..however smtp port is open and I can telnet to it

$ telnet xxx.xxx.xxx.xxx 25
Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx.
Escape character is '^]'.

/var/log/maillog shows some warnings

When I comment out

smtpd_sasl_auth_enable = yes

in /etc/postfix/mail.cf

outlook was able to connect but gave error

The message could not be sent. The authentication setting might not be correct for your outgoing e-mail [SMTP] server. For help solving this problem, go to Help, search for "Troubleshoot Windows Live Mail", and read the "I'm having problems sending e-mail" section. If you need help determining the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was 'xxxxx@gmail.com'.

Subject 'kjhkjhkjh'
Server Error: 554
Server Response: 554 5.7.1 <xxxxxx@gmail.com>: Relay access denied
Server: 'mail.xxxxxx.com'
Windows Live Mail Error ID: 0x800CCC79
Protocol: SMTP
Port: 25
Secure(SSL): No

Moreover port 25 do not respond for localhost..I can telnet to port 25 outside the server..but not from localhost..

Please help me out in this situation.

Thanks.

What's in /etc/postfix/main.cf? What's the output of

uname -a

?
