I wrote some code to send email using the MailMessage object. It's working fine in localhost, but when I run the code on my development server I get no email.

What do I need to do to set up mail on the server?

Hi,

Any error.??

Or

Is Smtp is open for sendin mail

ask your hosting provider about the smtp port, sometimes you may need to use 2525 as the port 

I m writing a sample code for sending mail. Please recheck your mail coding...

using System.Net.Mail

Hi,

I have given a sample code below which would work from the development server. (if your company is using Microsoft exchange server)

Step 1:

Public Sub SendEmail(ByVal Toaddress as string, ByVal body as string, ByVal subject as string, ByVal ishtml as Boolean)

            Dim Msg As New MailMessage

                        Try  

                  Msg.From = New MailAddress(ConfigurationManager.AppSettings("EmailFromAddres").ToString, 

                                     ConfigurationManager.AppSettings("EmailFromAddressDisplayName").ToString)

                  Msg.To.Add(New MailAddress(Toaddress))

                   Msg.Subject = subject

                  Msg.Body = body

                  Msg.IsBodyHtml = ishtml

                  Msg.Priority = MailPriority.Normal

                  ' to connect to the exchange server by using info in the web.config

                  Dim client As New SmtpClient(ConfigurationManager.AppSettings("ExchangeServerName").ToString())

            client.DeliveryMethod = SmtpDeliveryMethod.Network

                  client.UseDefaultCredentials = True

                  client.Port = ConfigurationManager.AppSettings("ExchangeServerPort").ToString()

                  client.Timeout = ConfigurationManager.AppSettings("ExchangeServerTimeout").ToString()

                  'send the email

                  Try

                        client.Send(Msg)

                  Catch ex As Exception

                        Exit Sub

                  End Try

            Catch ex As Exception

            Finally

                  Msg = Nothing

            End Try

      End Sub

Step 2:

change your web.config to include the following information about your company's exchange server

<configuration>
     <appSettings>
        <add key="ExchangeServerName" value="CWcwcw"/>
        <add key="ExchangeServerPort" value="25"/>
        <add key="ExchangeServerTimeout" value="999999"/>
        <add key="EmailFromAddres" value="something@somedomain.com"/>
        <add key="EmailFromAddressDisplayName" value="Mr Someone"/>
        
    </appSettings>


</configuration>

Hope this helps.

Please let me know if you need any other help.

Sorry forgot to mention the below information:

please include the below lines at the top of the code behind page.

Imports System.Net.Mail
Imports System.Web.Configuration

What I've found in the past is that when I push to my development server, if the sender and receiver of the email are the same address, it will generally fail.  Try updating one or the other to see if that takes care of it.  You could also just try some different recipient addresses to see if they receive the emails.

On the shared hosting, most of the times they use a different smtp server other than the server they host your websites. So you cannot use local host as the SMTP server. You will have to find out and get the correct smtp server name from your host. Also, sometimes these smtp servers need a username/password and will not work with the default credentials. So ask your hosting provider for this information.

Finally, some hosters allow only mails to be sent from a Email address that is in the email accounts of the domain that you have hosted with them. So you might not be able to use different email address.

Thanks for all the replies. My problem was that the SMTP server setting in my web.config was not correct for the remote server.
