I want to send email by the outlook using smtp auth but I cant!

I run the command: zmcertinstall mta ssl/ssl/server/server.crt ssl/ssl/server/server.key with a root user, to generate smtpd.crt file. After that, the ZimbraAdmin web interface didnt work any more because a problem with the encryption. ?!?!

When I use Kmail client (TLS + Plain Text) I can send email, but with the Outlook didnt work.The follow messages appear in log:

"Jan 25 15:47:40 webmail postfix/smtpd[6381]: NOQUEUE: reject: RCPT from unknown[]: 504 <windows>: Helo commandrejected: need fully-qualified hostname; from=<fred@piraidigital.com.br> to=<fred@linuxsolutions.com.br> proto=ESMTP helo=<windows>"

But to correct this error, I need access the zimbraAdmin!!! And my firefox cant connect because the encryption problem. Who can help me?
