SMTP and IMAP settings
I've tried everything I can think of, read, or ask about, including the help fora. My Thunderbird settings no long handshake with Charter.com. I think IMAP might be okay, but SMPT is not. Every time I try a new fix, I get a different error message, although now they are whittled down to about 4. I'm ready to abandon Thunderbird, though I like its features more than any other provider's. Thanks for clear direction ... if there is any.
