Re-reading the above, I thought it could be worth to somewhat elaborate.

Once the file ~/_mailboxes/dovecot-acl-list has been created, it in  
fact becomes a SELECTable mailbox!
And it is impossible to get rid of it, as it is immediately re-created  
upon a LIST command:

	# telnet 127.0.0.1 imap
	Trying 127.0.0.1...
	Connected to localhost.
	Escape character is '^]'.
	* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
