How to send e-mail on ASP .Net using outlook address??
I've tried this code but no luck:
Dim mailMessage As System.Net.Mail.MailMessage = New System.Net.Mail.MailMessage()
mailMessage.From = New System.Net.Mail.MailAddress("fromAddress")
mailMessage.To.Add(New System.Net.Mail.MailAddress("toAddress"))
mailMessage.Priority = Net.Mail.MailPriority.High
mailMessage.Subject = "Subject"
mailMessage.Body = "test"
Dim smtpClient As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient("xxx.outlook.com", portNumber)
smtpClient.Send(mailMessage) //--> got error here
But while I'm execute the code, it got this error message:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.1 Client was not authenticated
I've tried to add a line of code:
smtpClient.Credentials = New System.Net.NetworkCredential(username, password)
But still can't send the e-mail.
Anyone can help?
Try smtpClient.UseDefaultCredentials = false; before you set new Credentials
Try to set smtpClient.EnableSsl to true / false depending on your environment
I'm guessing you are using Exchange 2007 or later as backend?
Anyway, your mail server does not allow you to send mails anonymously. You'll either need to supply a username/password in your code or allow unauthenticated relaying from your webserver.
Talk to your IT guys what they prefer.
I did it using c#.This may help you.Please check.
MailMessage msg1 = new MailMessage();
msg1.From = strEFrom;
msg1.To = strETo;
msg1.Cc = strECC;
msg1.Subject = "Hi";
msg1.Priority = MailPriority.High;
msg1.BodyFormat = MailFormat.Html;
msg1.Body = strBody;
SmtpMail.SmtpServer = ConfigurationSettings.AppSettings["MailServer"].ToString();
SmtpMail.Send(msg1);
and in web.config file
<appSettings>
<add key="MailServer" value=""/>
</appSettings>
Try these settings check for .EnableSSL property to true/false and the smtp post number on which your mail server listen for outgoing mail.
When you do not set enable the SSL settings in outlook for gmail outlook configuration then it gives same error but the reason was found the SSL settings..
well try this may it will solve your problem..
msg.IsBodyHtml = true;
msg.Body = mailContent;
SmtpClient mailClient = new SmtpClient("smtp.mail.yahoo.com", 25);
NetworkCredential NetCrd = new NetworkCredential(frmyahoo, frmpwd);
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = NetCrd;
mailClient.EnableSsl = false;
mailClient.DeliveryMethod = SmtpDeliveryMethod.Network;
mailClient.Send(msg);
if it does not solve your problem then check your mail server/ client for the problem.
public static bool SendMail(string mailAccount, string password, string to, string subject, string message)
{
try
{
NetworkCredential loginInfo = new NetworkCredential(mailAccount, password);
MailMessage msg = new MailMessage();
msg.From = new MailAddress(from);
msg.To.Add(new MailAddress(to));
msg.Subject = subject;
msg.Body = message;
msg.IsBodyHtml = false;
SmtpClient client = new SmtpClient("smtp.gmail.com");
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = loginInfo;
client.Send(msg);
return true;
}
catch (Exception)
{
return false;
}
}
I use this code to send mail from my gmail account.
was having the same error, moved the client.UseDefaultCredentials = false; before setting client.Credentials and everything works.

I'm getting the error "Server does not support secure connections" with my code below.
SmtpClient smtp = new SmtpClient();
MailMessage mail = new MailMessage();
mail.From = new MailAddress("*****#gmail.com");
mail.To.Add(recieverId);
mail.Subject = "Invoice Copy and Delivery Confirmation for booksap.com Order " + orderno + ". Please Share Feedback.";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment(Server.MapPath("OrderMail\\Invoice.pdf"));
mail.Attachments.Add(attachment);
MailBody = "We are pleased to inform that the following items in your order " + orderno + " have been placed. This completes your order. Thank you for shopping! ";
StreamReader reader = new StreamReader(Server.MapPath("~/MailHTMLPage.htm"));
string readFile = reader.ReadToEnd();
string myString = "";
myString = readFile;
myString = myString.Replace("$$Name$$", ContactPersonName);
myString = myString.Replace("$$MailBody$$", MailBody);
mail.Body = myString.ToString();
mail.IsBodyHtml = true;
mail.Priority = MailPriority.High;

smtp.EnableSsl = true;
smtp.UseDefaultCredentials = true;
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential("*******#gmail.com", "*******");
smtp.Send(mail);
mail.Dispose();
mail = null;
How can I fix this issue?
If I set
EnabledSsl = false
it will return the error: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.1 Client was not authenticated.
That error message is typically caused by one of the following:
Incorrect connection settings, such as the wrong port specified for
the secured or non-secured connection
Incorrect credentials. I would verify the username and password
combination, to make sure the credentials are correct.
if it is ok,I think you have to set DeliveryMethod = SmtpDeliveryMethod.Network
simply try this..
using System.Net;
using System.Net.Mail;
var fromAddress = new MailAddress("from#gmail.com", "From Name");
var toAddress = new MailAddress("to#example.com", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body
})
{
smtp.Send(message);
}
ALSO
Change account access for less secure apps
Go to the "Less secure apps" section in My Account.
Try Option 2:
#Abhishek Yes.The code that you have written will send the message to the server just check your mail box (***#gmail.com) but smtp client of google is preventing you from entering into thier domain.
You have to make your gmail less secure that is you need to allow sign in attempt.
Check Your mail box,you should have such response from gmail domain and you need to make your account less secure.
I think its about captcha and bots preventing such logging in,people who know can throw some light in these things.Make your account less suspicious.Hope this helps
If you are working in any specific domain(company) then might be the company have personal proxy authentication so you will have to bypass proxy authentication for prevent error.
first you need to add
smtpServer.EnableSsl = false;
then add below code in your web.config
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy usesystemdefault="True" bypassonlocal="True" />
</defaultProxy>
</system.net>
When a customer buys an item, the button should send an email to the website owner. Here is the code I currently have:
SmtpClient smtpClient = new SmtpClient("smtpout.europe.secureserver.net", 80);
smtpClient.Credentials = new System.Net.NetworkCredential("info#furkantellioglu.com ", "Password");
smtpClient.UseDefaultCredentials = true;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
MailMessage mail = new MailMessage();
mail.Body = "Bekleyen Siparişleriniz Bulunmakta Lütfen Kontrol Ediniz.";
mail.Subject = "Dermabon Web Satış";
mail.IsBodyHtml = true;
mail.From = new MailAddress("info#furkantellioglu.com", "Sipariş");
mail.To.Add(new MailAddress("info#furkantellioglu.com"));
mail.CC.Add(new MailAddress("f.tellioglu#gmail.com"));
smtpClient.Send(mail);
But when I run it I get this error:
An exception of type 'System.Net.Mail.SmtpException' occurred in System.dll but was not handled in user code
Additional information: Sunucu güvenli bağlantıları desteklemiyor.
Any ideas on what this means?
please try changing
smtpClient.EnableSsl = true;
to
SmtpServer.EnableSsl = false;
a similar thread has been discussed on this forum which might help you Link
the error message means the server does not support secure connections. Your are using enable ssl but sending to port 80 so there could be a conflict here.
seems like a port error, try using changing
EnableSsl=false; and or UseDefaultCredentials = true; or use port 25
I have functionality in my site which sends a email to an id .. Email contains a link to a webpage and a security key .. But the problem is it goes into the junk folder
I'm using free hosting by Somee.com
Code:
MailMessage message = new MailMessage();
message.IsBodyHtml = true;
message.Body = ("Copy The Link And paste It In Them follow Link Download </br>"+ encoded_url);
message.From = new MailAddress("lz-wag#hotmail.com");
message.To.Add(TextBox2.Text);
message.Subject = user + " Has Share The File With You";
try{
SmtpClient client = new SmtpClient();
client.Host = "smtp.live.com";
client.EnableSsl = true;
System.Net.NetworkCredential networkcred = new System.Net.NetworkCredential();
networkcred.UserName = "lz-wag#hotmail.com";
networkcred.Password = "password";
client.Port = 587;
client.Credentials = networkcred;
client.Send(message);
sendFile.Visible = false;
Label1.Visible = true;
Label1.Text = "Your File Has Been Shared";
}
catch(Exception ex){
Label1.Visible = true;
Label1.Text = "Your File Is Not Shared";
//Label1.Text = ex.ToString(); ;
}
Whether or not the email goes into the junk mail folder is a function of the email client, not a function of how you are sending the email.
However, FYI, both the MailMessage and the SmtpClient implement IDisposable, so should be in using blocks. Something like this:
using (MailMessage message = new MailMessage())
{
// ...
using (SmtpClient client = new SmtpClient())
{
// ...
client.Send(message);
}
}
I also suggest that you log the exception somewhere, or you'll never know what went wrong when something goes wrong.
I am able to send emails successfully from LocalHost.
After hosting my website i am unable to send.
The following is the error:
System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. ha10sm40374374pbc.23 - gsmtp
can anyone help me to solve this.
Below is code:
public void SendMail(string ToMail, string subject, string Message)
{
// Gmail Address from where you send the mail
string fromAddress = "mygmailid#gmail.com";
// any address where the email will be sending
//string toAddress = ToMail;
//Password of your gmail address
const string fromPassword = "********";
// Passing the values and make a email formate to display
//string subject = subject;
string body = "\n\n"+Message;
// smtp settings
var smtp = new System.Net.Mail.SmtpClient();
{
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
smtp.Timeout = 20000;
}
// Passing values to smtp object
smtp.Send(fromAddress, ToMail, subject, body);
}
Google sent a mail with the subjact "Suspicious sign in prevented"
I selected it's me only option.
Then changed the Gmail password and used it in the application .
Now able to send the mails from the production server also...
Try below code:
using (MailMessage mailMessage = new MailMessage())
{
mailMessage.From = new MailAddress(email);
mailMessage.Subject = "YOUR_SUBJECT";
mailMessage.Body = "YOUR_MAIL_BODY";
mailMessage.To.Add(new MailAddress("RECIPIENT_EMAILID"));
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.EnableSsl = true;
System.Net.NetworkCredential NetworkCred = new
System.Net.NetworkCredential();
NetworkCred.UserName = "SENDER_MAIL";
NetworkCred.Password = "SENDER_MAIL_PASSWORD";
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Send(mailMessage);
}
After invoking above method GOOGLE or GMAIL will send you one mail regarding security (To allow the less secure app to configure mail) then allow that one.
