I have been fighting this for a while but I do not receive emails from people with gmail accounts. My email service is from gmx.com that I access from thunderbird. Several months ago I suddenly stopped getting my wife's emails. She now texts me if she needs to send me something. Now the same problem with my daughter's gmail account. I have not received emails from some others that are probably also gmail accounts. I don't seem to have a problem getting emails from accounts other than gmail. If I go to the gmx site, the emails are there but they are not being downloaded by thunderbird. Thunderbird does download all the other emails, just not the ones from gmail accounts. I have checked my message filters and there are no filters that reference gmail. How can I fix this?
