Comment 16 for bug 148207

Jack, there is no support for Thunderbird, as in, no code ever written to handle it. For logging, you can edit $HOME/.config/tracker/tracker.cfg and change Verbosity to 3 (max) and you will find logs for trackerd, tracker-indexer and tracker-extract all in $HOME/.local/share/tracker/.

You might want to disable evolution if you are finding you have email issues right now you should be able to do this with the tracker-preferences application or by running trackerd -d evolution or by changing the config file.
