Suggestion Rated 5 out of 5 stars
This is the most convenient anti-spam email addon I've tried so far. However, I suggest the same things as Toni said. And additionally I recommend to use a drop down list in the options. This way it is much easier to add more services. At the moment, the options dialog gets more and more confusing, because you use a tab for each service to switch to its preferences. That uses a lot of space. With a dropdown list of services that switches the options field, it would be much easier. Also you would have more space then to use the tab switching for the global preferences.This review is for a previous version of the add-on (0.2.7.0).
I have added support for mailcatch.com in version 0.2.7, which should be available here shortly.
I don't speak French so couldn't figure out tempomail, and guerrillamail did not work when I tested it.
Let me know if this works for you!
