I think the main problem for your listener is that it's not defined if
it should be run before or after the event listener that Enigmail
specified. There is no guarantee of any sequence.

If I were you, I'd hook on some other event that is triggered earlier,
like observing "mail:composeOnSend".

In addition, I'd make sure you also activate the option to ignore
per-recipient rules. But as John said: you may be better off by just
using the per-recipient rules ...
