            mail.To.Add(new MailAddress("indra.rikkala@achirconsultancy.com"));
           
            mail.Subject = TextBoxSubject.Text;
            mail.Body = TextBoxMessage.Text;

        SmtpClient client
            = new SmtpClient("smtp.achirconsultancy.com");

        try
        {
           
            client.Port = 25;
            client.Send(mail);

What exception you are getting?
Is the port open? Firewall permissions in place?
Further make sure you have configured SMTP configuration in Web.Config:

<system.net>
   <mailSettings>
     <smtp from="abc@somedomain.com">
       <network host="somesmtpserver" port="25" userName="name" password="pass" defaultCredentials="true" />
     </smtp>
   </mailSettings>
</system.net>

If needed, have a look at this Microsoft Video tutorial:

If needed, there are lots of article on this very site on how to send emails

Is it mandatory to include SMTP configuration details in web.config.
I am pretty sure I have achieved it even without that.exception was connect failure.

Is that mean the in credential section I am giving wrong details?

Solution 5

I don't see anyplace in your code where you set the Host property of the client object. That's required, along with the Port property that you have set. Check here[

Why backslashes before apostrophes?

Roger Wright 26-Jun-10 10:42am

I didn't put them there. It's a bug I reported last night, possibly something related to using Opera for posting here. When I type it and preview it, the post looks fine, but when it appears the slashes are inserted. I suspect that Chris has reverted to VBScript again...
