Hello ! I need help with relay configuration. I use hmailserver, configured according to the instructions. When sending a message through the email client, the message is being sent in the Hmailserver logs, but this message does not appear in the queue dynu.com. I always get back an error message, see below. Could you help me with this configuration please. Thank you !

If you have SMTP relay subscription for domaina.com, you can only send emails from name@domaina.com. If you try to send emails from name@nameb.com, you will see the 'invalid from address' error.
