Looks like some input stream seeking optimizations are broken (when one input stream reads from another, which reads from another, ...). I already managed to fix the performance problem, but now it's corrupting saved mails sometimes. So a while longer to get it fully fixed :) And since it's a pretty big change, I'm not sure if I want to risk breaking v1.2 by changing it, so maybe it's v2.0 only.
