Asked this question before but never received a response. When someone sends me an email from their gmail account, thunderbird dopes not download it from the server. I use gmx.com for my email. All other emails sent to me are downloaded by thunderbird but not ones sent from gmail accounts. It is not a problem with gmail because if I use the web access, the email is on the server but is not downloaded by thunderbird. I have checked the filters in thunderbird, there is no reference to gmail. The odd thing is that I have a second email account, also on gmx and thuderbird does correctly download the emails sent from gmail accounts. Any idea how I can solve this problem?
