how to check smtp server configuration in linux?

The first step is to check the mail server’s configuration file. This will be located in /etc/mail/ or a similar directory. In this file, you will need to look for the following lines:

SMTP server:

This should be the address of your SMTP server. If you do not know this, you can try using a tool like MxToolbox (https://mxtoolbox.com/) to look it up.

SMTP port:

This is the port that your SMTP server uses for communication. The default value is 25, but some servers use a different port.

Once you have located these lines, you can then use a telnet client to connect to your SMTP server on the specified port. For example, if your SMTP server is at smtp.example.com and the port is 25, you would run the following command:

telnet smtp.example.com 25

If the connection is successful, you should see something like this: 220 smtp.example.com ESMTP Postfix
