Rated 4 out of 5 stars

The add-on works well in TB 5.0. However I would like some more flexibility. For example, if sender = xxx then use template abc. This would be very useful if you are, e.g., subscribed to a mailing list in a foreign language.

This review is for a previous version of the add-on (0.7.4). 

Thank you for your review and your suggestion for improvement. If is possible then we thinking about your suggestion for improvement (we will check). FACT: Smart Template 4 can't support Thunderbirds address book this is working with Binary Code and needed Informations you can't catch with an Addon (Javascript). BTW: Smart Template 4 is more flexible then other Addons that are made for Custiomize your Mailheaders (eg. Change Quote)! By this reason i can't understand that you give only 4 Stars...
