Hi,
I just tried it; it didn't give any error neither did it do anything.
What could be the problem?

@:Emmao
Hi Emmao, did you changed mail address in to field ?
MailMessage mail = new MailMessage();
mail.To.Add("jainamit.agra@gmail.com");
Hi,
I tried the code but is giving an error:-
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 209.85.147.109:25"
thanks in advance
@Anonymous:
The error you are referencing is error from Server's of google , it's not related to code
Check your internet connection, and check the username and password of gmail account you are using to send mail
Hope this solves your problem , do let me know if you face any other problem

@Elumalai k : you can do it in two ways , 1. use asp.net membership provider 2. use your own table to check username and password
for second option create a table for storing username and password and then write code in Click event of Login Button like this
private void btnLogin_Click(object sender, EventArgs e)
{
if (txtLogin.Text == "")
{
lblMessage.Text = "User Name cannot be blank";
}
if (txtPwd.Text == "")
{ lblMessage.Text = "Passoword cannot be blank"; }
if (txtLogin.Text != "" && txtPwd.Text.Trim()!= "")
{
CheckLogin();
}
}
private void CheckLogin()
{
string strLogin = txtLogin.Text.Trim();
string strPwd = txtPwd.Text.Trim();
try
{
string[] tables = null;
DataSet objDs = new DataSet();
string strQuery = "Select * From [password]" +
" Where user='" + strLogin.Trim().ToString().Replace("'", "''") +
"'" + " And Pass='" + strPwd.ToString().Replace("'", "''") + "'";
objDs.Fill(strConnString, CommandType.Text, strQuery, objDs, tables);
if (objDs.Tables[0].Rows.Count>0 )
{
Response.Redirect("Default.aspx");
}
else
{
lblMessage.Text = "Incorrect Login information!!!";
}
}
catch (Exception ex)
{
throw new Exception("The method or operation is not implemented.");
}
}
i got this error when i run above code(The remote certificate is invalid according to the validation procedure.)in last line
smpt.send(mail)
mr.amit plz reply me at himanshu.kaushik04@gmail.com
waiting for ur reply
@himanshu:
Remote certificate invalid error suggests your system date might be wrong
Check your system's date and set it to current date and year , check your gmail account username and password and try the code again
Do let me know if you still face the problem
hello, amit thanks its working now
but can u give me the code of simple mailing in asp.net with c# not with gmail
in simple emailing i m getting the error
Mailbox unavailable. The server response was: 5.7.1 Unable to relay for himanshu@saibaba.com
waiting for ur reply
thank u so much
@himanshu:
For sending mail without using gmail, you need to have your smtp server configured on your system
Check your smtp server and pop server settings
Hi,
when i'm running your code in the server at godaddy i get this error message: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 209.85.199.111:25"
But when running at my computer is works ok.
Have any idea what the problem is?
Best regards,
Miguel
hi amit,now i can send email in asp.net but cant receive. coz i dont hv coding for this can send me plz how to receive the mails.
can u send me receviing coding
thanks u r the best
@Miguel:
This is probally issue of your hosting provider , u can ask them
HI i tried your code it is working on a normal net connection but on a proxy server sending fails
can u tell me what extra things to add so that we can send mails on a proxy server
thanks!!
@Ankit:
Add this in your application's web.config file.
<system.net>
<defaultProxy>
<proxy proxyaddress="YourProxyIpAddress"/>
</defaultProxy>
</system.net>
And change this line of code in code behind
smtp.Host = "smtp.gmail.com";
to
smtp.Host = "smtp.gmail.com,587";
do let me know whether it fixes your issue or not ?
Thanks for the reply,
i added the proxy address in web.config file and added smtp.port=587
but problem still continues :(
@ankit:
Check whether port 587 is open on your system or not ? it might be blocked by your sys admin or by any firewall
try this code
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = False;
smtp.Credentials = new System.Net.NetworkCredential
("YourUserName@gmail.com","YourGmailPassword");
smtp.EnableSsl = true;
smtp.Send(mail);
let me know the exact error you are getting
this works well with any smtp server but not with gmail
sorry I commented anonimously earlier, your most recent settings do work, thanks
thx alot, amiT jaiN !!! =D
btw.....can u teach me how to get the server status?
im a fresh grad from m'sia....asigned to create a program to auto generate an email when the server is down....
i got no idea where to start......
i look forward to hearing from you.THANKSSSS...
yajie_2248@hotmail.com
Thanks amit. That's very useful tips. Afterall, I would like to express one thing: what is the difference in magnitude in using my own smtp sever and going for my google account? Could I use google account for my production environment also [I don't think so, however]?. Thank you.
@Sangam:
U can use either smtp or gmail , the difference is , in case u don't have smtp server configured or up and running, or somehow ur smtp server is down than u can use gmail

Dim mail As MailMessage = New MailMessage()
mail.To.Add("abcd@gmail.com")
mail.To.Add("abc@hotmail.com")
mail.From = New MailAddress("abcd@gmail.com")
mail.Subject = "Email using Gmail"
Dim body As String = "Hi, this mail is to test sending mail"
mail.Body = body
mail.IsBodyHtml = True
Dim smtp As SmtpClient = New SmtpClient()
smtp.Host = ("150.123.123.132")
smtp.Port = 25
smtp.Credentials = New System.Net.NetworkCredential("150.123.123.132\administrator", "12345")
smtp.EnableSsl = True
smtp.Send(mail)
Getting Error "Failure sending mail."
Any Suggestion?
Thank you
ASAM
@Atif:
You need to use your gmail email id and password in below mentioned line of code
System.Net.NetworkCredential("150.123.123.132\administrator", "12345")
System.Net.NetworkCredential("yourmailid", "yourpassword")
@amiT jaiN
good day. how can i attach documents in my email, using the code you've provided?
I am unable to use. Getting error :
Mail Sending failed.A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
@Above : this seems a problem with your internet connection , u can try the the with ssl enabled and changing port to 587, also make sure u have enabled pop mail forwarding in your gmail account settings
can u plz check the following code i am trying it but unable to send mail, its not giving any error
protected void btnSendmail_Click(object sender, EventArgs e)
{
MailMessage message = new MailMessage();
try
{
MailAddress fromAddress = new MailAddress(txtEmail.Text, txtName.Text);
message.To.Add("basit_systemist@live.com");
message.Subject = "Feedback";
message.From = fromAddress;
message.CC.Add("king_basit@hotmail.com");
message.IsBodyHtml = false;
message.Body = txtMessage.Text;
SmtpClient smtp = new SmtpClient();
smtp.UseDefaultCredentials = false;
smtp.Host = "smtp.gmail.com";
smtp.Port = 25;
smtp.Credentials = new NetworkCredential("syedbasitalishah@gmail.com", "roseandjasmine");
smtp.Send(message);
lblStatus.Text = "Email successfully sent.";
}
catch (Exception ex)
{
lblStatus.Text = "Send Email Failed.
" + ex.Message;
}
}
}
Sending mail through any of the mail server needs only 3 values.
1)SMTP server name
2)Port
3)SSL flag value.
If you have configured outlook then you might know it.
