"No valid recipients" is probably a SMTP 554 error code output, i.e. the mailserver doesn't like the recipient mail address, or there's some unmet conditions.

If the communication is in plaintext, run a packet capture and have a look at what's happening there.

Well, the mail server says it's unwilling to relay emails for "email001@email.com.br".
Anyway, you need to check with the administrator of that mailserver and discuss with them what needs to be changed.

Thanks,

The FortiAuthenticator IP was not allowing on the SMTP server. Before, there was a NAT IP allowed. Included IP in SMTP relay. It worked.
