configuring SMTP server
 

configure SMTP mail service according to the following requirements

1. mail server should accept mail from remote hosts and local hosts

2. a user natasha must be able to receive mail from local hosts

3. mail delivered to natasha should spool into the default mail spool for user sumit, /var/spool/mail/natasha

I googled general SMTP server installation and got these two step-by-step instructions. See if it helps.

More information would be needed if you specific questions about your operating systems. Good luck.

You forgot step 4:
4. DO YOUR OWN HOMEWORK
