Can't download mail from server
I use a private email server (mail.ragan.us. I have set up Thunderbird on Linux Mint 22 with the same email server settings I use on Outlook in Win 10 and Apple Mail on IOS 26 which both work fine. I created the account in Thunderbird and it showed success. When I try to get mail for gary@ragan.us,Thunderbird shows connected to mail.ragan.us, but will not download mail from that server. Any suggestions? Thanks.
