OOPS! This is a simple configuration error. I did not realize that Firefox cached my default "mailto" application as a preference. I further did not notice, after clicking on "mailto" links, that the mail composition client window was Evolution (not Thunderbird).
Fix: In Firefox, select "Edit/Preferences". Select the "Applications" tab, then find "mailto", and select "Thunderbird". ** Changed in: evolution (Ubuntu) Status: New => Invalid -- Messages sent in Thunderbird get stuck in Evolution outbox https://bugs.launchpad.net/bugs/658427 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evolution in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
