Hi Azeem

and For Sending Mail used Following code Successfully Worked With Gmail Server

<system.net>
        <mailSettings>
            <smtp deliveryMethod="Network">
                <network host="smtp.gmail.com" port="587" defaultCredentials="false" userName="[email protected]" password="mypass"/>
            smtp>
        mailSettings>
    system.net>

And Code used to Send mail is Below

        using System.Net.Mail;

        SmtpClient sc = new SmtpClient();
        sc.EnableSsl = true;
        MailMessage mail = new MailMessage(new MailAddress("[email protected]"), new MailAddress("[email protected]"));
        mail.Subject = "Testing ";
        mail.Body = "Hello This IS Testing ";
        sc.Send(mail);
        Response.Write("Mail Sent Successfully !!");

Ok Try this Idea Remove all those Mail Settings From Web.Config and Embed them in your Coding use Directly below Code to Send mail
```
 protected void btnSendMail_Click(object sender, EventArgs e)
    {
        SmtpClient sc = new SmtpClient("smtp.gmail.com", 587);
        sc.EnableSsl = true;
        sc.Credentials = new NetworkCredential("[email protected]", "mypassword");
         
        // Be Sure Where you Send mail to Check if Mail is Sent or Not 
        MailMessage mail = new MailMessage(new MailAddress("[email protected]"), new MailAddress("[email protected]"));
        mail.Subject = "Testing ";
        mail.Body = "Hello This IS Testing ";
        sc.Send(mail);
        Response.Write("Mail Sent Successfully !!");

    }
```

Hi ,

Not all fields are mandatory in web.config. Please find below code you need to update in web.config and ur application.
Web.config:
<system.net>
<mailSettings>
<smtp>
<network host="host server name" port="25" defaultCredentials="true"/>
smtp>
mailSettings>
system.net>

Application:
SmtpClient smtp = new SmtpClient();
     smtp.UseDefaultCredentials = true;
     MailMessage mailMessage = new MailMessage();
      mailMessage.To.Add( new MailAddress( ToemailAdresss,
                      ToDisplayname);

                //create the mail message
                mailMessage.Subject = subject;
                mailMessage.Body = messageBody;
                mailMessage.From = new MailAddress( fromEmailAddress,
                    fromDisplayName );
                smtp.Send( mailMessage );
for above to work please add
System.Net and System.Net.Mail namespaces.

Please mark this post as anwer if this is helpful.
Happy Coding!!

Hi, Azeem

Check Port No if you are using smtp.gmail.com server then Check the port in Web.Config

Port = "587"

and in Username =your gmail whole email Address like "[email protected]"

and in password = your gmail account password

and Be also make Sure that you have enabled POP support in your Gmail account

if you not have enabled POP in gmail account

Do it

1. Login to your gmail account

2. Click on Settings

3. go to Forwarding and POP/IMAP tab

4.Select radio button "Enable POP for all mail"

Thanks

Happy Coding :)

i make ssl enable but its not working on server
Kirtan Patel17y ago
It Depends on Mail Server

as Majority Mail Services like Gmail uses ssl so have to make this option enable .

Happy Coding :)

i type nslookup on the command prompt as you set i got some message that
Cannot find server name for ip address 192.168.56.200:non existent domain
Default server:some name
address: some ip address
i got the above information
Roei Bar17y ago
hey, the from is not a must field, you can enter it dynamicaly from your code, this is the from email address, you must insert a valid email address that has "send permissions" on the host part you need to go to : command -> type nslookup -> set type=mx -> write down your mailserver name whatever you receive is the mailserver host this is the mx record
