I went about attempting to setup the gmail account option described here but Google is now removing the ‘less secure apps’ option in May 2022. So people should avoid the GMAIL smtp option. I’ve gone ahead and updated the email sending option in the wiki and included an example for Mailgun (which is what I use for my own business) in case people want to use that.
I don’t know if that clickatell and sms stuff is even used anymore on that wiki page but I left it in there just in case.
