Would need to change everywhere that it's being called, add a deprecation and
work with both values for now.
Looks like `:username` is found more often in the codebase 334 times compared
to `user_name` coming in at 231.

At first it appeared to me in the smtp settings, the username has to be
specified as "user_name", but the comment in the source is naming it
"username".
* :user_name - If your mail server requires authentication, set
the username in this setting.
