I'm trying to copy a local folder containing some larger mails (few MB) to a DavMail-IMAP-EWS folder using Thunderbird 17 and DavMail 4.3.3-2164-trunk. But after a minute Thunderbird aborts with a time-out. I have selected setting 'Enable KeepAlive'.
I see there's a class 'MessageLoadThread' that prevents IMAP timeouts for loading large messages. But should there be a separate 'MessageSendThread' or so for this situation?
