There is no reason why a '.' should be disallowed. *IF* this is the  
configured separator on your IMAP server, it would create a sub-folder  
structure. If it is NOT the separator, then there is no reason why it  
should fail.

Please enable IMAP debugging (see imp/config/backends.php) and provide  
the IMAP log of when this fails. Also check other horde/webserver  
error logs for any relevant entries.
