A library for setting up Ruby objects as test data.

Mail::Message#raise_delivery_errors

If set to false, mail will silently catch and ignore any exceptions
raised through attempting to deliver an email.

This setting is ignored by mail (though still available as a flag) if you
define a delivery_handler
