When I sending a message to certain domain I get this error: 530 5.7.0 Must issue a STARTTLS command first. and the message it´s not delivered to the destiny.
But when I send the same message to the same destiny from Yahoo or Gmail; for example, the message reaches its destination without problems.
What it´s the issue in this case....?
Thanks in advance

I'm guessing that whatever server you're sending to requires TLS for message transmission. Do you have Outbound SSL enabled in Queue Manager settings?
Don't forget to restart the service after making settings changes.
