AUTH LOGIN

[michaelmaitland]

we need to implement an authenticated login because most emails require authentication before we can send an email. Below is an example using telnet of me sending an email using an AUTH LOGIN. Note that i used "<--- comment here " to describe what was going on. I also removed the usernames and password and email addresses used for privacy reasons and replaced them with [description of what was replaced]

What kind of authentication? Just username/email and password?

yea just username and password. Most SMTP these days won't work unless we have a login and password even though old SMTP allowed it
