If you saw the Part 1 of the previous video in this series here you can now enjoy more insights and bemusement into our ancient e-mail insights and some comments and factiods.
This is from a series called Database and explores sending email in 1984 and just highlights how far we've come in terms of technology and just how ubiquitous e-mail has become in modern day business and life.
E-mail evolved from ARPANET who used it in network based and was initially exchanged on APRANET as extensions to the FTP but today is carried out by SMTP.
You can test if you email server is up and working correctly using the command line (run as Administrator) and I'll detail the instructions below:
Connect with telnet using the following command:
telnet examplemailserver.com 25
Type ehlo examplemailserver.com. (Some servers also accept helo command in place of ehlo)
ehlo examplemailserver.com
Type mail from: username@examplemailserver.com:
mail from: username@examplemailserver.com
Type rcpt to: somebody@outlook.com, my-friend@yahoo.com (replace with your actual recipient names):
rcpt to: somebody@outlook.com,my-friend@yahoo.com
To write your message type the data then followed by your subject and message. To end the message, put a period on a line by itself and press enter:
