SMTP server

[Mohammed Shahidul Islam]

Hi
I am using linux AS 3 as proxy server. I can not send my mail using proxy due to SMPT port disabled.

How i make my linux box as SMTP server and enable SMTP port ?

Please advice me.

Hello Mohammed,

please check with the command "netstat -tulpen" if a daemon is bound to port 25/tcp. If not, please check die init.d directory for a script called "sendmail", "exim", "postfix" or "qmail". RHEL should normally use sendmail as MTA. So try the command "/etc/init.d/sendmail start". After that you should have a running MTA on you machine. To configure sendmail, check the documentation for it.

Hope this helps.

Best regards,
Patrick

Shalom,

See that the iptables firewall configuration ((iptables -L )) permits port 25.

Sendmail is installed by default on this OS.

chkconfig sendmail on

http://www.sendmail.org to learn how to make it safe.

Thanks a lot
I checked but no 25/TCP port enable.
I need to enable SMTP port only.
Please suggest me on this regard

if you start the sendmail daemon, it will open the 25 port.

Also check there is uncomment line in front of 25 port from /etc/services file.
