gmail -> gmail: required special treatment?

Dear Sebastian,

Thank you so much for your fast response!

This was fixed in the commit by me from yesterday:

Excellent! I just got the latest (v6.5.1.2-1-gb5a1315) and tried it and it
indeed does not create the folders on the "remote" side anymore - yeah!

I now get some "new" error messages about UIDs not mapping though. What can
I do to help debug this? I have copied the tty output of the process below.
What else can I do?

Ok! Will I need to read into the current way of doing things at length
before I can touch anything without breaking things, or should I just start
fiddling? If you think I should read up before touching anything, are there
any key documents / code regions I should start with that you can recommend?
If you think I am more likely to cause harm than help by poking around in
the code myself, would anyone else perhaps be interested in giving this a
go? I would be most enthusiastic about helping try/test/validate this at
least.

Many thanks again for everything
and best wishes,
David
