That's kind of what I was trying to say :-) It's only a help to me if 
I'm not making the proxy and it handles more IMAP issues than my own

Yes, from my perspective an IMAP->IMAP proxy would actually be more 
useful since it would allow me to tell users to use the proxy whenever 
some weird IMAP issue was not handled well by MailMate :-)

Also, as soon as multiple JMAP implementations exist then some of them 
are likely to be buggy or limited in some way -- and then I'm making 
workarounds again...

What is really needed is a comprehensive test suite which users can 
*easily* use to test a given IMAP provider. It kind of 
[exists](https://imapwiki.org/ImapTest/ServerStatus), but it's too hard 
to use. I'm thinking something like what the [acid 
tests](http://acid3.acidtests.org) did for web browsers.
