Its the same on my local machine and on some server i am using. Also when applying netstat -nltp |grep master
i have the same output on both server and local:
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 29325/master
tcp6 0 0 :::25 :::* LISTEN 29325/master
and when sending email from local machine using:
echo 'test' | mail -s 'test' [email protected]
its working 100% and i recieve email directly; but its not working when i try to do the same thing on the server.
any help would be appriciated. thanks
