I have used Netscape for many years. And Thunderbird. I installed Mobile Thunderbird a few weeks ago on my Android phone, importing the settings from my desktop Thunderbird. Everything work, just that ALL my sent messages disappear. They reach their destination, but I can’t see them in any sent folder on the phone. Is this a bug? I have checked, that «Subir los correos enviados» (= upload sent messages) is checked. It was already checked. I unchecked, sent mails, no change. Re-checked, sent mails, no change. Ideas? Also my «bandeja de salida» (outbox I think) is empty. Only my Sent and sent-mail folders have mails (one seems from the desktop thunderbird, the other from the webinterface).
