Hi,
Turned off extensions in the FetchResponseEncoder.java and now it is
starting to work normally in Lotus Notes and I can open messages.
However, I get a NPE for some messages (multipart I think) as follows:

The new code seems to be better structured and more efficient. It is
more stateless and commands are not created for every request for
example. I think it is quite important to try and keep it stateless and
not create loads of objects all the time. For a couple of reasons,
memory consumption and speed.
I think the code is more scalable now where each request is basically
independent, before it seemed to be more sticky sessions like, or I have
misunderstood it:-)
The APIs have also improved a lot in the new implementation.
Thanks
/Martin

i'll take a look at that now
(https://issues.apache.org/jira/browse/IMAP-91)
if you do figure out some selective way to do this, that'd be great.
maybe we could talk clueful clients into user a new USER_AGENT
extension command...

how are you finding the new code?
