How to Set Up and Configure SMTP server

Hello everyone,

Nowadays, I'm trying to send an email over Unix/Linux server. As you know, we can understand mail configuration is correct or not correct by using following cmd command in Windows -> telnet your-mail-host.com 25 helo your-domain-name.com mail from: [email protected] rcpt to: [email protected] data Hello. This is a test. . quit

I would like to ask that how can I understand in Unix/Linux server in similar way. Besides, If I need to set up and configure SMTP server how can I carry out this process. Could anybody help me, please ?

Thank you
