[MlMt] new subfolders -- MailMate or Dovecot problem?

[Steven M. Bellovin]

To try to shrink a too-large folder, I created 15 subfolders.  For 11 of 
them, though, the Dovecot IMAP server did not get the name that the 
creating instance of MailMate has; instead, I see subfolders with names 
like .foo.Untitled, .foo.Untitled-1, etc. This is true on the Dovecot 
server and hence on other mail servers.

So: I have two questions. First, why did Dovecot not get the proper 
names from MailMate? Second: what's the best thing to do to solve the 
problem? Rename them on an affected MailMate machine?
