I was going to test 1.1.16 so as to see how it handles global ACLs (in
the hope to have a possible comparison with 1.2.0's odd behavior),
when I encountered the problem described hereafter.
Note that just disabling ACLs is sufficient to get back a fully
functional imap binary.
So, should there be some plans for a 1.1.17 version, perhaps could the
info provided here prove somewhat useful.
Folowing telnet session:
# telnet 127.0.0.1 imap
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Dovecot ready.
a1 login testuser ******
a1 OK Logged in.

yields this in mail.log:
