[LUAU] help on port 25

[goku ball z]

Hi dave, I am able to send mail out... thats no problem... =)  but when sending mail back that is when I run into problems..... 
  the suse firewall has port 25 open and in the /etc/services the port 25 is open.. Also when I do a netstat -ant port 25 is in LISTEN mode. So I know that the port is ok... =)  

  check this out.....So when I use the domain name it does not work.... I just can't understand that....
  hope you can help.... thanks
   
  test /home/goku> telnet localhost 25
Trying 127.0.0.1...

  firewall settings? /etc/hosts.deny? Or most probably the default
config of your mail daemon is set not to relay. Any of these could be
what's up.

If you want to test your mailer, why not just send yourself some email?

echo 'testing 123'| mail -s 'testing123' your.email at address

Not sure where suse puts the mail logs by default, but if you have a
problem that is the place to look. Or the firewall might cough into a
more general system log.

Are you sure you *want* port 25 accepting incoming non-local
connections? It's just an invitation to spammers to use your cycles
and bandwidth and start other trouble.
