Can't send emails to hotmail and yahoo

I'm testing my new web site from my local computer, i can send emails to my DASP domain emails account. However, i couldn't do the same thing with hotmail and yahoos.

 

smtp.[MyDomainName].com, which hosted by DASP.NET

 

Yes, i have tried that. Plus, when i send an email to [email protected] it went out smoothly.


The problem occurs when i send emails to Yahoo, Hotmail, etc

 

the error states:


"Mailbox unavailable. The server response was: [email protected] No such user here."

 

Imports System


Imports System.Net.Mail


Imports System.Web.UI


Imports System.Web.UI.WebControls


Imports System.Web.UI.HtmlControls


Imports Microsoft.VisualBasic


Public Class Utilities


Public Shared Sub SendMail(ByVal From As String, ByVal ToEmail As String, ByVal Subject As String, ByVal Body As String)


Try


Dim MailClient As New SmtpClient(XanMartConfiguration.MailServer) ' My SMTP SERVER IS "smtp.MyDomainName.com"


Dim MyMailMessage As New MailMessage(New MailAddress(From.Trim).ToString, New MailAddress(ToEmail.Trim).ToString, Subject, Body)


MailClient.Send(MyMailMessage)


Catch ex As Exception


MsgBox(ex.Message.ToString) ' To Test


End Try


End Sub
EndClass


My SMTP isstored in the web.config file

Thank you for your patience.

Hi,
Please take a look at the code I posted in this thread:
http://community.discountasp.net/default.aspx?f=24&m=25440
Salute,
Mark

 

Here is the error message:


"Mailbox unavailable. The server response was: <[email protected]> No such user here."


And my web.config section:


<system.net>


<mailSettings>


<smtp from="">


<network host="smtp.MYDOMAINNAME.com" port="25" />


</smtp>


</mailSettings>


</system.net>


The reason i did not use "localhost", cuz, i'm testing my web site from home computer.


Thank you in advance.

 

So what might be wrong?


what might be relevant?

 

Hi,
There are many things that can go wrong.
What errors are you getting now?
By the way, what does your SMTP section of your root web.config look like?

Should look like this:

 

Hi,
SMTP will fail locally unless you create the services.
On the DASP server you do have to use the settings I posted above, not your domain name.

Note: You can run simulated tests locally with the method below but it's kinda wacked.
