Hi,
I want to send mail from linux to gmail server but am getting delivery failed mentioning "Connection refused."

But I am able to send the mail to yahoo server.

Can anyone help in setting for gmail server and how can I send mail to official gmail account.

Are you sending mail from a system which is having a static IP address?

Try the following tutorial:

No, we have dynamic IP address.

Also, the link you provided states to install using yum and this yum command is not working in my Linux session.

How can I install package without yum?

What distro are you using?

Where do you see this error message?

By default, most Mail Transfer Agents (MTA) come with a default configuration that specifies the use of DNS lookups for external mail delivery. The MTA will attempt to connect directly to the MX servers for the domain in question (gmail.com in this case), but since you're using a dynamic, public IP, most servers on the Internet will have been configured to reject the connection as a anti-spam measure.

You will probably need to configure your MTA to use a "smart host"; a relay server provided by your ISP specifically to avoid this issue. As for how you do this, that would depend on which distribution/MTA you're using.

decenter,
I am using RedHat Linux 4 Enterprise edition

Ser Olmy,
I am not sure which distribution/MTA I am using.

Can you help me out with this?

I'm not sure of RHEL 4 but try to use up2date utility to install the packages (I think there will be similar packages in the RHEL 4 repository).

On running up2date, I am getting "OpenSSL.SSL.Error".

Any idea regarding this?

According to this article, RHEL 4 includes no less than 3 MTAs: sendmail, postfix and exim. The default is sendmail, but apparently one can use the "Mail Transport Agent Switcher" GUI application or the system-switch-mail-nox terminal command to select another MTA.

To make sendmail use a Smart Host, edit the /etc/mail/sendmail.mc file and add the line:Replace isp-smarthost.isp.com with the fully qualified domain name of the Smart Host server provided by your ISP. Important: You must use the exact same quote characters as in the example above; mix up single quotes and backticks and it just won't work.

Once you've done that, you must run the make command in the /etc/mail directory and restart sendmail with service sendmail restart.

Ser Olmy,
Can you provide some example as am new to this.
