I have an account in Thunderbird which has not been checked for a long time (I've been using Gmail, which doesn't delete any messages from the server). So this means when I click "Get Mail" it starts fetching 2500+ emails!
I'm wondering, how do I stop or pause all those mails coming in? I have it set so it doesn't pull them in automatically on startup. But once I've clicked "Get Mail" there does not seem to be a way to stop it, besides quitting Thunderbird entirely.
My main motivation for wanting to pause fetching is that a lot of the email is spam so I'd like to pause and mark a bunch of emails as spam, then continue fetching with hopefully further email being marked as spam automatically.
