    Various fixes for userid with dots and unixhierarchysep
    Use correct (not internal) userid in ACLs when creating root level folder.
    Fix ACLs setting when userid contains dots.
    In pop3d, as for imapd, correctly handle userid with dots.


Fixing the various unixheirsep and altnamespace cases to work correctly has been on my todo list for far too long.

Anyone who's following along with 2.5 development and uses either of those two set to other than the default - I'd love your test results and bug reports.  I really want this rock solid by release.

(anyone who can write test cases would be greatly appreciated too!)

Thanks,

Bron.
