I'm having trouble setting up a custom domain in WorkMail as it wouldn't even let me send and receive messages. Configure the logs in Route53 and the problem of receiving mail is solved, but I still cannot send. In WorkMail/Domains everything appears verified except this option. enter image description here
When I send the mail it throws me this error enter image description here
My question would be if it is a misconfiguration of DMARC or SMTP, because all the guides that AWS gives me point to creating the records and configuring DMARC. Or anyway, what is the problem I'm having?
