If you're using JangoMail to send transactional email, and specifically you're using the SMTP service to send transactional messages, then this post applies to you!
When using the SMTP service, you no longer need to specify your From Addresses in your JangoSMTP Settings when using SMTP Authentication (SMTP AUTH) to authenticate into relay.jangosmtp.net.
This is a substantial enhancement to the JangoMail SMTP service. By simply setting your email client to use SMTP AUTH and passing in your JangoMail username and password, the system will be able to assign your emails to your account. This is especially beneficial to organizations that send emails from many different From Addresses through one single JangoMail account.
As a result, we will soon be taking away the screen within Settings where you would normally specify a list of From Addresses when using SMTP username/password authentication.
Note that this only applies to users using username/password to authenticate into the SMTP server. If you're using IP authentication, then there is no change, as users using IP authentication have always been able to send without specifying From Addresses.
