POUpdating Legacy Code from System.Web.Mail to System.Net.Mail in Visual Studio 2005: Problems sending E-Mail
text
Body
copied!<p>Using the obsolete System.Web.Mail sending email works fine, here's the code snippet:</p> <pre><code> Public Shared Sub send(ByVal recipent As String, ByVal from As String, ByVal subject As String, ByVal body As String) Try Dim Message As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage Message.To = recipent Message.From = from Message.Subject = subject Message.Body = body Message.BodyFormat = MailFormat.Html Try SmtpMail.SmtpServer = MAIL_SERVER SmtpMail.Send(Message) Catch ehttp As System.Web.HttpException critical_error("Email sending failed, reason: " + ehttp.ToString) End Try Catch e As System.Exception critical_error(e, "send() in Util_Email") End Try End Sub </code></pre> <p>and here's the updated version:</p> <pre><code>Dim mailMessage As New System.Net.Mail.MailMessage() mailMessage.From = New System.Net.Mail.MailAddress(from) mailMessage.To.Add(New System.Net.Mail.MailAddress(recipent)) mailMessage.Subject = subject mailMessage.Body = body mailMessage.IsBodyHtml = True mailMessage.Priority = System.Net.Mail.MailPriority.Normal Try Dim smtp As New Net.Mail.SmtpClient(MAIL_SERVER) smtp.Send(mailMessage) Catch ex As Exception MsgBox(ex.ToString) End Try </code></pre> <p>I have tried many different variations and nothing seems to work, I have a feeling it may have to do with the SmtpClient, is there something that changed in the underlying code between these versions?</p> <p>There are no exceptions that are thrown back.</p>
