Your account has been unsuspended and the mailbox passwords for all of your mailboxes have been randomized. You'll need to reset your mailbox passwords to use them.
I also removed the forwarder from diretoria@escolasmt address. Forwarded emails count as sent messages (and you had 4 recipients, so each email it received caused 4 emails to be sent). We highly recommend not using forwarders, as just receiving mail will cause you to exceed your mail limit through no fault of your own. Users are limited to 50 sent emails per day for the entire account, so with that forwarder, receiving just 13 emails would've caused you to exceed the limit.
