From: Eric on 23 Apr 2010 03:10 Hi, I'm working on a ASP.Net website where I use the MailMessage method to send a report filled in by the user to a given email address. The user can also upload an attachement to be put in the data part of the report. If the attachement is less then 1,7 Mb there is no problem, the email is sent. Any larger attachement and I get an error stating "the message could not be sent" The webserver is an IIS7 and I use the local smtp server (via IIS6) to send the emails. In the settings of the smtp server I have unchecked the email size limitations. At first I had it set to 8192 Kb, but for testing I removed the limit. Unfortunalty the emails are not sent, I don't even see them appear in the mailroot/queue folder. (the smaller emails I do see) I have put the timout property of the SmtpClient to 300 secs, so it should have enough time to send the message. What is going wrong here? Dim smtpC As SmtpClient Dim message As New MailMessage message.To.Add(New MailAddress(rc.sEmailOntvanger)) message.From = New MailAddress(rc.sEmailZender) message.Subject = "RIE report for site " & rc.sSitenummer message.Body = strbody.ToString message.BodyEncoding = System.Text.Encoding.Unicode message.IsBodyHtml = True message.Attachments.Add(data1) data1 = Nothing 'attach PDF file to message Dim RapportPDFName As String = Server.MapPath("~\") & FormFile.Replace("/", "\") data1 = New Attachment(RapportPDFName, MediaTypeNames.Application.Octet) Try ' Add time stamp information for the file. disposition1 = data1.ContentDisposition disposition1.CreationDate = System.IO.File.GetCreationTime(RapportPDFName) disposition1.ModificationDate = System.IO.File.GetLastWriteTime(RapportPDFName) disposition1.ReadDate = System.IO.File.GetLastAccessTime(RapportPDFName) Catch ex As Exception ClientScript.RegisterStartupScript(Me.GetType(), "alert", "<script>alert('Error');</script>") message.Dispose() data1 = Nothing disposition1 = Nothing Exit Sub End Try message.Attachments.Add(data1) data1 = Nothing smtpC = New SmtpClient("localhost", 25) smtpC.UseDefaultCredentials = False smtpC.DeliveryMethod = SmtpDeliveryMethod.Network smtpC.Timeout = 300000 Try smtpC.Send(message) message.Dispose() disposition1 = Nothing data1 = Nothing Catch ex As Exception message.Dispose() disposition1 = Nothing data1 = Nothing ClientScript.RegisterStartupScript(Me.GetType(), "alert", "<script>alert('Het was niet mogelijk om het rapport te emailen. -1-" + smtpC.Host + "');</script>") Exit Sub End Try rg, Eric

ASP.Net bears very little resemblance to classic ASP so, while you may be lucky enough to find a dotnet-knowledgeable person here who can answer your question, you can eliminate the luck factor by posting your question to a group where those dotnet-knowledgeable people hang out. I suggest microsoft.public.dotnet.framework.aspnet or the forums at www.asp.net. ****************************************************************** > where I use the MailMessage method > to send > a report filled in by the user to a given email address. > The user can also upload an attachement to be put in the data part of > the report.
