I have been trying to solve my problem earlier, through “sfhowes” but had to interrupt for the holidays. As I understand I now have to start a new question. My email program is “runbox.com” that I have used for several years getting my email through Thunderbird and I never had any problems. Then I end up in the hospital just as Runbox subscription ran out. I now have Runbox again and have no problems but I can’t get my mail through Thunderbird. The settings are the same. Both incoming and outgoing mail is: mail.runbox.com. What can I do now?
