If you are using Postfix then you don't need sendmail. Shut it down.
Is the firewall up and running? If yes is port 25 allowed through?

[nova168168]

the firewall always turn off , and sendmail is too , but i still can't telnet the port 25 , what's wrong ?

Silly question but is postfix running? i.e. post the output of "service postfix status"

First stop sendmail:
service sendmail stop

Then start postfix:
service postfix start

Then try again (oh and to make sure your firewall is off give us the output of "service iptables status")

THX , the postfix is running , but still can't send out the email
telnet port 25
220 rainbowgroup.com.mo ESMTP Postfix
ehlo localhost

250-ETRN
250-ENHANCEDSTATUSCODES

250 DSN
quit
221 2.0.0 Bye

So it looks like the SMTP server is running now (which wasnt the case in your first post?). What happens if you telnet to it and type "VRFY user" where user is a valid user on the system?

What mail client are you using?

[nova168168]

What happens if you telnet to it and type "VRFY user" where user is a valid user on the system?

yes , the system reply
>252 2.0.0 user

What mail client are you using?
i'm using windows live message to test , anything wrong ?

[DT0X]

i'm using windows live message to test , anything wrong ?

To be honest I would have no idea where to start - my first response would be this isnt possible but I know nothing about windows live messenger!

Sounds like your mail server is working, try sending mail from the command line - why are you using live messenger?

I tried to use the command line already ! the result is shown as below :

220 rainbowgroup.com.mo ESMTP Postfix
helo localhost
250 rainbowgroup.com.mo

250 2.1.0 Ok
rcpt to:nova168168@hotmail.com

Look mate Im trying to help you here but using exclamation marks as if Im the one asking stupid questions isnt going to help - basically all your doing is telnet to port 25 and sending the requests individually - while this may prove something thats not what I mean, funnily enough this being a linux forum, when I said try sending mail from the command line I mean try sending mail from the linux command line e.g.

mail user

at the linux CLI
