Moving messages between servers with different configurations

[Marc Roos]

This pulls over the whole test mailbox, but I need it to be stored in a 
different mailbox, of course that is now possible to move from the local 
test to the local INBOX/test2. But then I might aswell scp the mbox in 
the first place. 

Should we conclude that it is not possible with a single doveadm command 
to move messages from RemoteServerA/usertest/mailboxA/messagesof2017 to 
LocalServerB/usertest/mailboxX/ ?
