Code looks about right to me. Your localhost is probably not configured correctly. Is it ur machine or host? Check the mailroot folder in inetpub folder and check for your mail there.

Also, i would suggest looking int System.Net.Mail instead of web. Its a lot better.

I configured my localhost added 127.0.0.1 in RELAY.
when i checked my mailroot folder i can see all my mails in Badmail folder…

I did this, but i got few errors like no defenition for SmtpMail.send(mail) in System.Net.Mail

My general Question:
i’m a professional php programmer, in how many days cal i excel .net technologies? please let me know, as i’m having less exposure to OO Programming.
Many Thanks.

Hii.
That is working well when uploaded to the server.
My doubt is, i would now like to display a success or error message on top of the form for, if an email was sent or not.
How should i do this? can anyone please help me out…
Above is my C# code, i need to display Success Message in the form if all goes fine else error in GREEN color.

Why do not you try sending emails using SMTP authentication using SmtpClient class??

Just put a div on the page where ever u want the message to appear. Make it runat server and give it an id. and make visible=“false”

Then on success just divID.Visible = true. divID.InnerHtml = “Email has been sent”;

Just after the SmptClient.Send() method.

It could not be going out from local host as its a spam IP address. Wen i test in our local office, it doesnt work and I checked and my IP was on a spam list. But always works fine on live server
