Review for SendVia by p1nh3a6
Rated 4 out of 5 stars
Great and simple but now I prefer to use SMTP Control Extension (https://addons.mozilla.org/en-US/thunderbird/addon/7376) far way better to control SMTP Servers.
This review is for a previous version of the add-on (0.9.4).To create your own collections, you must have a Mozilla Add-ons account.
