You need to use authentication for the emailbox that we host for you.
SMTP Server: mail.YourDomainName
User Name: Use your full Email Address: someone@YourDomainName
Password: Email Password for : someone@YourDomainName
From address must be the same as your email address.
We can help you if you open a new request from your Control Panel -> Help&Support section and write steps to simulate the problem on our side.
