Because of some frustrations with Mac Mail, I switched to Thunderbird which I've used in the past.
Unfortunately, it only downloads some of the emails. If I check on the server, there are still emails waiting to be downloaded. If I open Mail, it will download all the email. But Thunderbird won't do it.
In an attempt to solve the problem, I have turned off all junk mail controls in both the server and local folder settings for Thunderbird. But I still can't get them.
What can I do?
