MA TLS smart host

Hi, I need to configure, only output, the SMTP smart host to TLS.

EMC, I configured what was possible, but the stakes in what remains. user and pw are correct.

the error is "'451 4.4.0 Primary target IP address responded with:" 451 5.7.3 Require basic authentication. "Attempted failover to alternate host, but That did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts "

yet the utenticazione is configured.

thanks
