HTML Email Help

I am trying to send an email automatically when a user has filled in a web form.

I have been using the contents of each textbox so that the email can display details of a specific order. For example, txtForename.text, which could contain "Jerry".

I have been trying many different ways to rectify the error, with now luck.

My code looks like this:

' Send Email to customer
Dim Mail As New MailMessage()
Mail.To = lblEmail.text
Mail.From = "rentals@dotnet.itags.org.OCR.com"
Mail.Subject = "Rental Details"
Mail.BodyFormat = MailFormat.Html
Mail.Body = "<h1>Rental Summary</h1><hr /><table width='100%'><tr><td colspan='2'><h2><u>Personal Details</u></h2></td></tr><tr><td></td><td></td></tr>" & _
"<tr><td width='9%'><b>Name:</b></td><td width='91%'>" & lblForename.text & lblSurname.text & "</td></tr><tr><td></td><td></td></tr><tr><td><b>Address:</b></td><td>"& lblAddress1.text &"</td>" & _
"</tr><tr><td></td><td>"& lblAddress2.text & "</td></tr><tr><td></td><td>" & lblCounty.text & "</td></tr><tr><td></td><td></td></tr><tr><td><b>Post Code:</b> </td><td>" & lblPostcode.text & "</td>" & _
"</tr><tr><td></td><td></td></tr><tr><td><b>Tel No:</b></td><td>" & lblTelNo.text & "</td></tr><tr><td></td><td></td></tr><tr><td><b>Email Address:</b> </td>" & _
"<td>" & lblEmail.text & "</td></tr><tr><td></td><td></td></tr></table><br /><table width='100%'><tr><td colspan='2'><h2><u>Purchase Information</u></h2></td>" & _
"</tr><tr><td width='10%'></td><td width='90%'></td></tr><tr><td><b>Car:</b></td><td>" & lblCarModel.text & "</td></tr><tr><td></td><td></td></tr><tr><td><b>Price:</b></td>" & _
"<td>" & lblCarPrice.text & "</td></tr><tr><td></td><td></td></tr><tr><td></td><td></td></tr><tr><td><b>Accessory Name:</b></td><td>" & lblAccessoryName.text & "</td></tr><tr><td><b>Price:</b></td>" & _
"<td>" & lblAccessoryPrice.text & "</td></tr><tr><td></td><td></td></tr><tr><td><b>Pickup Date:</b></td><td>" & lblCollectDate.text & "</td></tr><tr><td></td><td></td></tr><tr><td><b>Return Date:</b></td>" & _
"<td>" & lblReturnDate.text & "</td></tr></table><br />"
SmtpMail.SmtpServer = "localhost"
SmtpMail.Send(Mail)

I have created the email in a table format as you can see. I don't think there is any errors in the email structure. However, I am getting the following error:

Server Error in '/' Application.

I would appreciate any help anyone could give me!

You need to pass username/pass to your SMTP or adjust the SMTP to allow your access.

There was a post yesterday with the exact syntax for passing the credentials, but basically that's all it is.

Thats great thanks for your help!

I will try it out!
