Comment (by desrosj):

 [attachment:"41750.2.diff"] updates the `MockPHPMailer` class to extend
 the `PHPMailer` class at the correct new namespace.

 Also, it looks like PHPMailer now includes its own `Exception` class that
 is used by default. The only thing that class does is wrap exception
 messages in HTML. [attachment:"41750.2.diff"] adds a preceding `\` to all
 `Exception` occurrences to use the globally namespaced `Exception`
 instead.

 There are still some unit test failures that need to be investigated.
