I have about six email accounts on my Thunderbird. One is associated with my internet provider. The rest are related to my website server. All of the accounts. except one, are working fine. The one that isn't working somehow lost its password. Its an account related to my website. For a while I could get incoming mail but I couldn't reply. I changed the password at my web host, and now I can't receive or send. What do I need to do to restore this mailbox's functionality? Many thanks for your suggestions
