Lutos-Notes to Cyrus

[Lincoln Zuljewic Silva]

it works...
first I run:
./imapsync --host1 192.168.4.60 --user1 teste --password1 felicidade
--host2 192.168.4.35 --user2 lincao --password2 x --folder INBOX
--sep1 " "
to sync just INBOX

and after:
./imapsync --host1 192.168.4.60 --user1 teste --password1 felicidade
--host2 192.168.4.35 --user2 lincao --password2 x --prefix2 INBOX.
--exclude INBOX --sep1 " "
to sync and create the original tree of notes on cyrus
