I am using Thunderbird 18.104.22.168. I installed my gmail accounts first,
and now it is using those settings as the default server. I can't
change them for my other accounts (hotmail and work email), so
naturally, the emails from those accounts won't download. I tried
deleting the gmail accounts and reinstalling Thunderbird, but it still
defaults to gmail. How can I change it to not default to gmail?
