Well, so far so good. I've been using IMAP to access my Gmail for just short of a week now and haven't hit any real problems. Things were a bit slow at first as Thunderbird built the index of the folder contents, but once done, all seems ok.
The one thing that did annoy me for a while was Thunderbird wasn't checking all my Gmail folders/labels: it was only checking the Inbox.
I use a lot of filters on Gmail, so it's important this works. I know you can right click on each folder, go to properties and select "Check this folder for new messages", but this is tedious with a lot of folders. I also know I can setup client side filters, but once again, this becomes tedious on multiple computers.
So, back to our good friend Google for a quick search and I found what I was looking for. In order to get Thunderbird to check all IMAP folders for new mail, just add the following to your
user.js file and restart:
You can also do this directly in the Config Editor (Thunderbird 2.0 and later) by going to
Edit -> Preferences -> Advanced -> Config Editor and searching for the above setting.
Now I have Thunderbird and Gmail working as I like it.
