First of all I'd like to thank you for your work.
Mark Hamlen is right. LookOut seems to have a problem with imap accounts, as long you not mark them as "use offline" and fully download the message.
So there is a possibility to workarround this issue. And I personaly think that this isn't really a BUG of LookOut, yust a "how to set up a working configuration" thing.
