Last night after a bit of "fun and games" I managed to get my website http://www.alex-parks.org/ upgraded to .NET Framework 2.0 on GoDaddy.  And generally I'm happy.

Unfortunately though sending emails using System.Net.Mail doesn't work, so the site can't send out emails when people register etc.  Obviously this has to be addressed.

At the moment I have "smtpout.secureserver.net" with port 80 set on the SMTPClient object (I have to set *something* or there is an error message that says SMTP server is not specified), and the error message I get is

"Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

On .NET 1.1 I didn't have to set the SMTP details, it just "worked".  If anyone knows how to get this to work on GoDaddy it'd be much appreciated, I can't believe I'm the only one.

Many thanks

Just thought I would update to say that I've gone back to System.Web.Mail for the time being.

Fortunately this still seems to work, despite the warnings the compiler gives about obsolescence. 

Normally I have Option Strict On which had stopped my web app compiling because of the use of System.Web.Mail.

However, after loosening the compiler it's now OK.  But I look upon this as a short term solution and I'd still appreciate any answer to get it working with System.Net.Mail.

I'm not a VB person but looking at the MSDN documentation for this
http://msdn2.microsoft.com/en-us/library/system.net.mail.smtpclient.aspx

I would guess that your host and port properties are not set correctly.  Just a guess based on the port 80 referenced above (SMTP runs over TCP/25)

Below is an excerpt from MSDN on the SmtpClient call.

To construct and send an e-mail message by using SmtpClient, you must specify the following information:

• The SMTP host server that you use to send e-mail. See the Host and Portproperties.

• Credentials for authentication, if required by the SMTP server. See the Credentials property.

• The e-mail address of the sender. See the Send and SendAsync methods that take a from parameter. Also see the MailMessage.From property.

• The e-mail address or addresses of the recipients. See the Send and SendAsync methods that take a recipient parameter. Also see the MailMessage.To property.

• The message content. See the Send and SendAsync methods that take a body parameter. Also see the MailMessage.Body property.

Posting again to say I have found the solution ! 

After doing more Googling around, it seems that smtpout.secureserver.net was not the correct outgoing server to use, since using this comes back with error messages such as "Mailbox name not allowed" and "not allowed in the list of rctphosts" and such.

The answer is to use an alternative called relay-hosting.secureserver.net.  Therefore the code below below should work for you as it now does for me :-

Dim objMailMessage As New System.Net.Mail.MailMessage

With objMailMessage
    .IsBodyHtml = False
    .From = New MailAddress("fromaddress@youremailaccount.com")  
    .To.Add("destinationaddress@whoever.com") .Subject = "Your Subject"
    .Body = "Body Text"
End With

Dim objSMTPClient As New System.Net.Mail.SmtpClient("relay-hosting.secureserver.net", 25) objSMTPClient.Credentials = CredentialCache.DefaultNetworkCredentials objSMTPClient.DeliveryMethod = SmtpDeliveryMethod.Network objSMTPClient.Send(objMailMessage)



I'm very glad you found a resolution to the problem.  Many thanks for posting back with your solution!

 

The solution was nice but I moved to c#. :S I gotta go find a c# version did you find any good sites for this. They cant be that hard to google. Just wondering in your search if you found anything worth while.

I am having the same issue.
Trying to send mail with .NET.MAIL via GODADDY.COm SMTP relay service.

My code still gives me the same error:

Hello,

Check the following from my hosting KB

Note: You should have POP email/pass with godaddy

 

Regards

Yes, I figured out how to use Credentials last night. I specified account that i created for SMTP relay, i even tried passing my domain as a 3rd optional parameter, still get the error that host is not allowed.
I think godaddy support rep hates me by now, for asking so many questions, but they have been very quick to respond as of today.
I host my site locally, so i am wondering if maybe i need to change some setting in IIS, but i belive setting defaultdeliverymethod=network should avoid going trough my local virtual smtp server.

There is one facet of GoDaddy that is somewhat annoying. They make you turn on SMTP email relaying and by default limit you to like 250 outgoing relays per day. You might want to check on your GoDaddy settings to make sure it's enabled.

I also have godaddy as my hosting and have found that I did not need to use the line of code about credentials.  It was working all along for me....I was not getting any errors but found that the test email  addresses I was filling into my form where being sent to my spam folder thats why I was not seeing them.  Below is my code that works hosted with godaddy:

Private Sub SendMail(ByVal from As String, ByVal body As String)

Dim mailServerName As String = "relay-hosting.secureserver.net"

Dim message As MailMessage = New MailMessage(from, "youremail@host.com", "", body)

Dim mailClient As SmtpClient = New Smtpclient

mailClient.Host = mailServerName

mailClient.Port = 25

message.Subject = "comments from my site"

message.Body = body

mailClient.Send(message)

message.Dispose()

End Sub

I had the same problem with "relaying denied from your location" and solved it by adding "auth login":

I have a free email account on a regitered godaddy domain let's call it myaccount@mydomain.com
myaccount is configured to allow SMTP relaying (not sure if needed) and I am _not_ using system.net.mail but instead a C# Mailer Example (http://www.aspemporium.com/) that uses sockets directly. You need to use "myaccount@mydomain.com" as the username and the same password used when loggin on the godaddy web-based mail.

here is the code:

        void SendMail()
        {
            //create and send a simple email with no attachments/

            // 2.) establish a connection to email server using sockets

I had somewhat the same types of issues using godaddy dedicated and Virtual dedicated hosting. Go Daddy Does not allow the use of port 25 unless it is used through their relay servers. In my case I have a corporate exchange environment in-house and I keep some simple web enviroments at godaddy.

So I needed my program to send email, however I wanted it to be sent using one of my exchange servers in-house.

Since Go daddy is blocking port 25 I was unable to get my smtp client to connect to my in-house exchange server. So I decided to bend the rules, I configured my exchange server with a second smtp port of 587 and set my smtp client to use that prot when sending the email.

Viola!.. works like a charm, here is a c# code example if that helps you understand.

I like godaddy for my domains but i would not like to use them for my hosting for reason such as this, i use webhost4life.com they are great.

Me too.  Very tired of trying to resolve this issue.  Any words of wisdom?  I've tried using different port numbers.  I've tried using different host names/strings.  I've tried miles and miles of code.  Currently using some code I picked up somewhere in this forum called MailHelper.  Also, forgive me if this is a totally stupid question, but in the Web.config file I included my username and password.  Isn't that a big security no-no?  What's protecting that info?

 Anyway...  here's my Web.config mail settings:

<

mailSettings>

<

smtp from="me@mydomain.com">

<

network host="relay-hosting.secureserver.net" port="3535" userName="me@mydomain.com" password="*******"/>

</

smtp>

</

mailSettings>
