        Hi,
that's true.

The old IMAP provider (before IMAP+) had a way to expunge "selected" 
messages, even without the extension (as not every server supports 
such extension then there should always be some fallback, right?) 
which was like "remove \Deleted flag from all messages which should 
not be deleted; call EXPUNGE; restore the \Deleted flag". The IMAP+ 
doesn't have any such code, if I recall correctly.

For the time being, expunge a trash folder, instead of the Junk folder.

By the way, On This Computer/Junk gathers messages from On This 
Computer folders only. The limitation is slightly lower in the stack, 
not only with the IMAP provider. I know there is filled an enhancement 
request to be able to expunge only selected messages (like delete in a 
Trash folder), which is similar to this expunge in a Junk folder, at 
least partially.
