SSRS Mail Configuration

Question

I use SSRS 2014 in a project. I created reports and i want send these reports with mail. This is my mail configurations:

<Extension Name="Report Server Email" Type="Microsoft.ReportingServices.EmailDeliveryProvider.EmailProvider,ReportingServicesEmailDeliveryProvider">
                <MaxRetries>3</MaxRetries>
                <SecondsBeforeRetry>900</SecondsBeforeRetry>
                <Configuration>
                    <RSEmailDPConfiguration>
                        <SMTPServer>mail.???.com</SMTPServer>
                        <SMTPServerPort>???</SMTPServerPort>
                        <SMTPAccountName>
                        </SMTPAccountName>
                        <SMTPConnectionTimeout>
                        </SMTPConnectionTimeout>
                        <SMTPServerPickupDirectory>
                        </SMTPServerPickupDirectory>
                        <SMTPUseSSL>False</SMTPUseSSL>
                        <SendUsing>2</SendUsing>
                        <SMTPAuthenticate>1</SMTPAuthenticate>
                        <SendUserName>report@???.com</SendUserName>
                        <SendPassword>???</SendPassword>
                        <From>report@???.com</From>
                        <EmbeddedRenderFormats>
                            <RenderingExtension>MHTML</RenderingExtension>
                        </EmbeddedRenderFormats>
                        <PrivilegedUserRenderFormats>
                        </PrivilegedUserRenderFormats>
                        <ExcludedRenderFormats>
                            <RenderingExtension>HTMLOWC</RenderingExtension>
                            <RenderingExtension>NULL</RenderingExtension>
                            <RenderingExtension>RGDI</RenderingExtension>
                        </ExcludedRenderFormats>
                        <SendEmailToUserAlias>True</SendEmailToUserAlias>
                        <DefaultHostName>
                        </DefaultHostName>
                        <PermittedHosts>
                        </PermittedHosts>
                    </RSEmailDPConfiguration>
                </Configuration>
            </Extension>

I saw that message:

Failure sending mail: The mailbox is unavailable. The server response was: 5.7.1 Authentication Required

I used that e mail configuration in other vb.net projects and it is successfully working. What is the problem in my codes?

Thank you.

From our experience, you have to use an internal SMTP server, we couldn't get this working with an external SMTP server so we had to install IIS 6 on another server, configure it with the external SMTP server account details and use that as an email relay for the reports.
