Re: setting *mailsubdir only if not set via client?

[Mark Crispin]

In my opinion, it's better to leave things alone and allow people to use 
Mail/ or whatever other subdirectory name they want.  For all you know, 
some power user may want to reference his home directory.

If you really want to go ahead with your intended strategy, then do 
something like the following early in routine mailboxfile():

  size_t i = mailsubdir ? strlen (mailsubdir) : 0;
  if (i && !strncmp (name,mailsubdir,i) && (name[i] == '/')) name += i + 1;
