I've moved over all emails from 10 accounts on one server to another. I use IMAP so this won't be an issue for myself, but someone else using these email accounts uses pop3. When I change the settings on their computer, Thunderbird will (I assume) download all the messages of the server, even though they are on their computer already.
Is there a way to force Thunderbird to only download emails from (for example) today as well as leaving messages on the server? We already have the "leave messages on the server" checked, but we don't want to download 10,000+ emails that were sent before today.
