NOTICE: Trial account does not have SMTP service. Therefore, you cannot test this in your trial account. We do this to prevent spammer from taking advantage of our Free Trial Service.
You should use the smtp server assigned to your account "mail.yourdomain.com" as the SMTP outgoing server for your web applications(Replace yourdomain.com to your own domain name).
To get your SMTP server setup, please follow the below:
1) Login to your control panel
2) Make sure a domain name is added to your account by going to Hosting Control Panel -> Website Domain Manager
3) Once the domain name is added to your account, go to Hosting Control Panel -> Email Manager and activate your email service for your domain name.
4) Create the necessary email account that you need. Your script MUST send from an valid Email account. So create the ones you need.
5) Done! Please follow below's code sample to send emails.
YOU MUST USE SMTP AUTHENTICATION
ASP.NET 2.0 (and later) has a built in class, System.Net.Mail, to send email.
VB.NET Code Sample
| <%@ Page Language="VB" %> |
| <%@ Import Namespace="System.Net.Mail" %> |
| <script runat="server"> |
|
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
ServicePointManager.SecurityProtocol = DirectCast(3072, SecurityProtocolType)
|
| |
| Dim strFrom = "[email protected]" ''IMPORTANT: This must be same as your smtp authentication address. |
| Dim strTo = "[email protected]" |
| Dim MailMsg As New MailMessage(New MailAddress(strFrom.Trim()), New MailAddress(strTo)) |
| MailMsg.BodyEncoding = Encoding.Default |
| MailMsg.Subject = "This is a test" |
| MailMsg.Body = "This is a sample message using SMTP authentication" |
| MailMsg.Priority = MailPriority.High |
| MailMsg.IsBodyHtml = True |
| 'Smtpclient to send the mail message |
| |
| Dim SmtpMail As New SmtpClient |
Dim basicAuthenticationInfo As New System.Net.NetworkCredential("[email protected]", "password")
''IMPORANT: Your smtp login email MUST be same as your FROM address. |
| |
| SmtpMail.Host = "mail.yourdomain.com" |
| SmtpMail.UseDefaultCredentials = False |
|
SmtpMail.Credentials = basicAuthenticationInfo
SmtpMail.Port = 25; //alternative port number is 8889
SmtpMail.EnableSsl = false;
|
| |
| SmtpMail.Send(MailMsg) |
| lblMessage.Text = "Mail Sent" |
| End Sub |
| </script> |

| <body> |
| <form runat="server"> |
| <asp:Label id="lblMessage" runat="server"></asp:Label> |
| </form> |
