I have a email account which did work fine till yesterday. Now I have to problem, that I can't download any mails with Thunderbird. It says that it is connecting with the server and then looking for new mails but then it just stops without doing anything. When using roundcubemail I see all the new mails that are correctly written into the mailbos but if I try to delete them they disapere from the screen but only until I refresh again. They don't go to the recycle bin. Any ideas? Thanks!
