    <p>I have a webform where someone can set up an account - I want to send them an email confirmation.</p> <p>The code I'm using:</p> <pre><code> // Create e-mail message MailMessage mm = new MailMessage(); mm.From = new MailAddress("OurOrganisationEmail@ourdomain.com", "Our Organisation"); mm.To.Add(new MailAddress("webuser@domain.com", "Web User")); mm.Subject = "Confirmation"; mm.Body = "You are now registered test"; mm.IsBodyHtml = true; // Send e-mail sc = new SmtpClient(); NetworkCredential basicAuthenticationInfo = new NetworkCredential(“OurOrganisationEmail@ourdomain.com”, “ourorganisationemailPassword”); sc.Credentials = basicAuthenticationInfo; sc.UseDefaultCredentials = false; sc.Send(mm); </code></pre> <p>web.config:</p> <pre><code>&lt;system.net&gt; &lt;mailSettings&gt; &lt;smtp&gt; &lt;network host="mail.OurOrganisationEmail@ourdomain.com" port="9999" userName="OurOrganisationEmail@ourdomain.com" password="OurOrganisationEmailPassword"/&gt; &lt;/smtp&gt; &lt;/mailSettings&gt; &lt;/system.net&gt; </code></pre> <p>But get:</p> <pre><code>System.Net.Mail.SmtpFailedRecipientException was caught HResult=-2146233088 Message=Mailbox unavailable. The server response was: Authentication is required for relay Source=System FailedRecipient=&lt;webuser@domain.com&gt; </code></pre> <p>Looks like it's wanting the user login details for the web address I'm wanting to send to. How can I amend this and send such confirmation emails like how all the other commercial companies do? </p>

    1. COIn NetworkCredential, did you try to use the real username, and not the user's email ? i.e "OurOrganisationEmail". (Also you should use code or config, but not both)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
