Hello, I am not able to send mails via Thunderbird (updated) for at least the last week. I have different accounts (web.de, one from my university and gmail), gmail is the only one that works also for sending Mails. Receiving Mails is no problem. When I try to send Mails, I received an error message saying "time out". I tried the points you mentioned in the FAQ Article (Settings for smtp, installing the account again, disable Avira, checking the online account of web.de, using thunderbird is allowed) Thanks!
