Hi all,

How do you send emails through code behind not using outlook, but through the SMTP server on the local server.

I need to send text emails, I can send HTML no probs.

The main problem I can see is that I have to send "��" special characters.

thanks,

Not sure if you are using asp.net 2.0 but there it is more than simple and it should not matter if you have umlauts in the Message Text.

Dim MailObj As New System.Net.Mail.SmtpClient
MailObj.Host = "localhost"
MailObj.Send(EmFrom.Text, EmTo.Text, EmSubj.Text, EmMsg.Text)

Thanks michael,

I am using asp.net 1.1.

What you have written is the same as I have, but for some strange reason I have always had the same problem. In HTML the emails are sent because I can use ä etc.

Okay, I changed the code back, so all HTML formating is now Text formating and it runs. Strange!!

Have you tried using the SmtpMail Object?


<%@ Import Namespace="System.Web.Mail %>
......
<%
Dim strEmailTo As String = "customer@example.com"
Dim strEmailFrom As String = "employee@example.com"
Dim strEmailSubject As String = "Importaint email!"
Dim strEmailBody As String

strEmailBody = "I'm just kidding! This message isn't really all that " & _
    "importaint. Thanks for your time!"

Send(strEmailFrom, strEmailTo, strEmailSubject, strEmailBody)

I only use the SMTPMail object.

I have written a wrapper for it so it's in German and some functions are easier to use.

I'm not using asp.net 2.0 and the above code fails with [ Compiler Error Message: BC30002: Type 'System.Net.Mail.SmtpClient' is not defined. ], is it only for 2.0?

I have included this [ <%@ Import Namespace="System.Web.Mail" %> ] on top and it still fails.

Here's my code:


  Sub ContactUs()
    Dim MailObj As New System.Net.Mail.SmtpClient
    Dim mFrom As String = " mailto:me@mlh.com - me@mlh.com "
    Dim mTo As String = " mailto:me@mlh.com - me@mlh.com "
    Dim mSub As String = "Subject line"
    Dim mMsg As String = "This is the message"
    MailObj.Host = "localhost"
    MailObj.Send(mFrom, mTo, mSub, mMsg)
    Response.Write(vbCrLf & "Email sent.")
  End Sub

I've got it now, I guess the above [ System.Net.Mail.SmtpClient ] is only for v2.0, I'm using the MailMessage() which brings me to my next question, which is the fastest and resourceless method to send simple text emails?

As far as I know the fasted (as in writing code) method is to use the System.Web.Mail.SMTPMail classes where this generates the fastest possible code execution is an entirely different matter. I have written a SMTP mail class that delivers directly to the mail host for the destination domain but this was to get the return codes from the remote system not to be fast. If your ultimate goal is to send bulk emails then an Ironport box is the solution but it's a huge investment that's only worth while if you can support the bandwidth that it will consume
