Also, I can't restart sendmail, it's freezing...(see below)

[root@pe-web init.d]# sendmail restart

Also, I tried this

It looks like yahoo are not accepting mail from your server. CAn you try a test to another email address? Hotmail or Google? It might be a good idea to configure your mail server so that the from email address is routeable. A lot of mail servers would reject email if this is not the case. Somebody@localhost is not a valid email address.

1. check. is it possible to send mail locally by

# mail -v user@loaclhost

2. then check the log /var/log/maillog for delivery success or not.

3. If it is ok. then u need to check with /etc/hosts, /etc/hosts.allow, hosts.deny

After I enter subject: testing....it has no response....
please help

[root@pe-web /root]# mail -v smmsp@localhost
Subject: testing

here is the maillog info. after I tried the above command. Thank you Please help...

Can you post the output of:

#chkconfig --list | grep sendmail

and

#service sendmail status

Thank you

NOt sure what Brian or barshani are trying to say, but your sendmail is up and running fine. Your mail server must answer with a proper dns name for a start. You can add this in /etc/hosts. Must be resolvable in dns

mail -v user@localhost
Subject: test --> (Press Enter)
. --> (Press .)
Cc: --> (Press Enter)
Null message body; hope that's ok

I found anohter post which is similar as my case. Finally, he made a port redirection from 25 to 26 and worked. Therefore, I did the same thing yesterday.

iptables -A INPUT -p tcp --dport 26 -j ACCEPT
iptables -A PREROUTING -t nat -p tcp --dport 26 -j REDIRECT --to-port 25

After I applied the iptables, it still doesn't work for me. Here is my maillog.Please help...Thank you

Thank you

i would reverse the firewall change you made. why did you make that?>>
Your mailserver appears to be working correctly.
All i can see is that some mail servers will not allow you to send mail to them because of RFC 821/822 (mailserver configuration).
thats all.
IF you are still having problems, you may have to pm me as this seems to be going a bit off track..
