sending an email from my webpage -- 101

I sent this simple email string. The response was that the user was "greylisted" ...


I sent the same email to [email protected] and the response was that [email protected] was not in the system.


---jim








string from = "[email protected]";


string to = "[email protected]";


string subject = "test email";


string body = "This is a test from GVOPS.COM?";


SmtpMail.SmtpServer = "webmail.gvops.com";


SmtpMail.Send(from, to, subject, body);

 

finally got it to work!! My lessons learned:


(1) I used the email manager at DASP and set the password. Login as [email protected] and go to the setting page to do this.


(2) use the web configuration wizard and set uo your smtp emil settings -- results in a web.congig section like this


<mailSettings>


<smtp from="[email protected]">


<network host="webmail.yourDomain.com" password="xxxxxxxx" userName="[email protected]" />


</smtp>


</mailSettings>


(3) first i tested this using the "password recovery" control in VS2008 --- this worked and sent me a new password to my email address -- no codeing!


(4) Next I sent an email from my C# codebehind.

{


Label1.Text = "welcome " + User.Identity.Name;


Profile.UserName = User.Identity.Name;


MailAddress to = new MailAddress("[email protected]");


MailAddress from = new MailAddress("[email protected]");


MailMessage message = new MailMessage(from, to);


message.Subject = "Using the new SMTP client.";


message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";


// Use the application or machine configuration to get the


// host, port, and credentials.


SmtpClient client = new SmtpClient();


Console.WriteLine("Sending an e-mail message to {0} at {1} by using the SMTP host {2}.",


to.User, to.Host, client.Host);


client.Send(message);





}


}

 

This is what was written to my web.config after I used the wizard.


<mailSettings>


<smtp from="[email protected]">


<network host="smtp.gvops.com" password="XXXXXXX" userName="[email protected]" />


</smtp>


</mailSettings>
Not sure about the write input for host, username, and pw -- i tried several versions.

I simply tried to get a loginpassword using the VS2008"password recovery" control. The system tried to mail me my password at [email protected] (my correct email) and the error is as shown below.

i read the KB and forum topics but cant get past zero.

I am using VS2008 (freebie) and used the wizards at ...
ASP.NET congiguration tool -> application configuration -> Configure SMTP e-mail settings

The requested info looks like the stuff provided below.
First question is, do I even need to fool with this? All I want to do is to send messages from my site (e.g, allow user to have his password sent to his address).

Choose this option if your e-mail server is on a local area network and you connect to it using windows credentials.

 

I was tearing out what hair I have left until I tried port 587.

If your config looks exactly like the one above but still doesn't work, you might want to try that. Mine now looks like this:




<system.net>


<mailSettings>


<smtp from="[email protected]">


<network host="smtp.mydomain.com" userName="[email protected]" password="pass" port="587"></network>


</smtp>


</mailSettings>


</system.net>
It'staking its own, sweet time to get the message out though... many many minutes before it appears.

 

In general the preferred smtp server to use when using web applications to send out email is 'localhost'. This will use the webservers smtp service to relay out the email. No login/password or port number is required when using 'localhost' as the smtp server.

Roger that, rcp. Works fine; thanks for that.


Saving the world, one line of code at a time.

 

actually u don't need to add anything in the web.config file,
just use this code behind :



Dim mm As New MailMessage(New MailAddress("[email protected]"), New MailAddress("ToAddress"))
mm.Subject = "hi"
mm.Body = "bla bla bla ,, "
mm.IsBodyHtml = False
Dim smtp As New SmtpClient
smtp.Host = "smtp.yourdomain.com"
smtp.Port = 587
smtp.UseDefaultCredentials = False
smtp.Credentials = New NetworkCredential("[email protected]", "password")
smtp.Send(mm)
