Title: Improving documentation for MailNotifier mode shortcuts and error messages on improper usage

This is a small fix which improves the error message emitted when 'all' is used in an iterator for the mode of the MailNotifier instead of a string.

It also changes the docs such that the different usage of 'all' is clearer.
