Hi,
When I use System.Net.Mail.MailMessage to send a message with a protocol-link in the body-html like this...
<a href="myProtocol://test">Click me</a>
... all I recieve is this...
<a>Click me</a>
The href part is gone.
I don't know if it's dotnet or outlook that is removing the href part.
Here's my sample code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.ClickDim mail As New System.Net.Mail.MailMessage
Dim smtp As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient("my_smtp_server")
With mail
.From = New System.Net.Mail.MailAddress('myemail@company.com')
.To.Add(New System.Net.Mail.MailAddress('myemail@company.com'))
.Subject = "Test"
.Body = BuildMail()
.IsBodyHtml = True
End With
With smtp
.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials
.Send(mail)
End With
End Sub Private Function BuildMail() As String
Dim sb As New System.Text.StringBuilder
sb.AppendLine("<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.0 Transitional//EN'>")
sb.AppendLine("<html>")
sb.AppendLine("<head>")
sb.AppendLine("<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>")
sb.AppendLine("<meta content='MSHTML 6.00.2900.2802' name='GENERATOR'>")
sb.AppendLine("</head>")
sb.AppendLine("<body>")
sb.AppendLine("<a href='myProtocol://test'>Click here</a>")
sb.AppendLine("</body>")
sb.AppendLine("</html>")
Return sb.ToString
End Function
How come that code removes the href part
Thank you in advance!!!!!!

Hi Mariya,
I get the same result as you. So I guess, that it's not dotnet messing up my links.
I've spoken with GFI (spam + anti virus vendor), they say it's not their products either ... hmmmm. I'm lost.
But thank you so much for helping me out here!!!!!
Kind regards,
Mojo

Hi Mariya,
Thanks for helping me out here!!
I did what you said, but I can't figure out how to read the tracelog. Can you help me and see if there's a problem here (I've blurred out the from at to sender adress):

I forgot to mention...
I've tried to use Outlook to send the link to myself, that worked perfectly, so I guess it must be a .net issue.

Mojo,
I'll send you an e-mail with the full log I got and info and how to read it. Basically in your log you're missing the socket info. To get it you need to add this part to your config file as well
<source name="System.Net.Sockets">
<listeners>
<add name="System.Net"/>
</listeners>
</source>
From the results I got we send the link fine. It could be that your e-mail server is removing them

Mojo,
I couldn't repro your issue: I send a message using SmtpClient using the exact same body and the whole link arrived as it was supposed to <a href='myProtocol://test'>Click here</a> It also showed on Outlook and Outlook express.
You can use a Netmon sniff or get a System.Net trace log and see what gets sent. Instructions on how to get a trace.log are here

Hello,
for me it worked without the
sb.AppendLine("<meta content='MSHTML 6.00.2900.2802' name='GENERATOR'>")
hope this helps
