Qmail x Zimbra

[maschimidt]

Hello everybody
I'm having trouble with my zimbra IMAP
I'm trying to migrate accounts from one server to zimbra imap qmail when tested IMAP access he always returns the following message

Escape character is'^]'.
* OK IMAP4 ready
. login teste01@mydom.org.br 1q2w3e @ # $
NO cleartext logins disabled
. BAD invalid command

I've used the following commands, but the problem continues, can someone help me?

zmprov mcf zimbraImapCleartextLoginEnabled TRUE
zmprov mcf zimbraPop3CleartextLoginEnabled TRUE

Thanks
