Accessing your gmail account from VPS using Mutt

I spent several frustrating hours trying to figure out what I was doing wrong after installing and configuring Mutt for Gmail.

$ mutt -s "Tester" bot.dude@gmail.com < /tmp/mail.txt 
msmtp: authentication failed (method PLAIN)

It turns out that Google prevents unauthorized access to your account and it will block mutt even if you have the correct user name and password. The only way to get past this hurdle is to let Google know to expect a login from what it thinks is a suspicious device (your VPS host). You can do that by going to the following link
