Naive and kinda silly workaround:
in `org.apache.james.imap.processor.AbstractMailboxProcessor#messageRange` in case of empty mailbox
(`selected.existsCount()`) replace empty optional with actual full range ("1:*"):
`Optional.of(MessageRange.range(MessageUid.of(lowVal), MessageUid.of(highVal)))`. Probably rather
inefficient as it would make actual retrieval?
PS. Is there a global logger of everything that James returns to the client (no idea what the
response is in this case :) )

Hi,
So I've been debugging issue with following error being returned when using Evolution on empty
mailbox. It requests "UID FETCH 1:*" -- not sure if that's correct (complete log below [1])
It should be handled in `org.apache.james.imap.processor.AbstractMailboxProcessor#messageRange` and
it returns `Optional.empty()`, because `selected.existsCount()` returns 0 (SelectedMailbox, empty
mailbox?)
On the face of it range `1:*` looks valid but IMAP is quite complex so I wouldn't be surprised if in
this case it wasn't.
Any hint how to deal with/fix that error correctly would be appreciated.
Btw. it would be handy if the log would contain complete received command, even for learning/
understanding better what's going on/what was received (for example UID fetch lacks actual parameters)
PS. Surprisingly Thunderbird doesn't trigger the error but looking at the logs it seems that's
because TB doesn't send `SELECT` command?
