It works fine for a particular email address, but rest of the emails dont works..following error shows up:
Server Error in '/RealTimeArsenicDataVisualizer' Application.
Mailbox name not allowed. The server response was: From address not verified - see http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html
my code:
System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient("smtp.mail.yahoo.co.in", 587);
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential(emailid, password);
client.Port = 587;
client.Host = "smtp.mail.yahoo.co.in";
client.EnableSsl = false;
object userstate = msg;
client.Send(msg);
Change your code to below:
client.Port = 465;
client.Host = " smtp.mail.yahoo.com";
client.EnableSsl = true;

this was my code for my local machine before my company switched to outlook 365:
SmtpClient SMTP Client = new SmtpClient(ConfigurationManager.AppSettings["EMailServer"]);
smtpClient.Send(message);
Since the outlook was changed, I google and find this code, however it does not work giving error code "Failed to send email" "General failure".
Please help me to resolve this issue
here is a new code:
SmtpClient client = new SmtpClient();
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredentmailial("email address", "network password");
client.Port = 25; // You can use Port 25 if 587 is blocked (mine is!)
client.Host = "smtp.office365.com";
//client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true;
client.TargetName = "STARTTLS/smtp.office365.com";
client.Send(message);
Thank you very much.
Vitaly.
This is the code I use to send the email using HOST smtp.office365.com
var fromAddress = new MailAddress("from#domain.com", "From Name");
var toAddress = new MailAddress("to#domain.com", "To Name");
string fromPassword = "Your_email_password";
string subject = "Test Subject";
string body = "Test Message";
var smtp = new SmtpClient
{
Host = "smtp.office365.com",
Port = 25, //Recommended port is 587
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body,
IsBodyHtml = true
})
{
smtp.Send(message);
}
Please check that is your port 25 is blocked by OS or not.
I'm trying to set up a email notification for a asp.net project, but it doesn't seem to work. On localhost it gives me the following error
5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM
while on azure it triggers a suspicious login message over and over.
I tried multiple suggestions:
port 25 instead of 587
UseDefaultCredentials true or false
enable and disable SSL
nothing seems to work. The suspecious activity mail is the closest I got so far. Here is my code
var client = new SmtpClient();
client.Host = "smtp.office365.com";
client.UseDefaultCredentials = false;
client.Port = 587;
client.EnableSsl = true;
client.Credentials = new NetworkCredential("Rachelle.XXXX#outlook.com", "password");
client.DeliveryMethod = SmtpDeliveryMethod.Network;
var message = new MailMessage("Rachelle.XXXX#outlook.com", "Rachelle_xxxxx#hotmail.com");
message.Subject = "a ticket has been changed";
message.Body = "Hi there, a ticket has been changed on Cronos. Please check Cronos for more details";
message.BodyEncoding = Encoding.UTF8;
message.IsBodyHtml = true;
try
{
client.Send(message);
return message;
}
When i send email there is an exception which says "failure sending mail".
var mailObj = new MailMessage("marabifuad2013#gmail.com", "to Email");
mailObj.Subject = "subject";
mailObj.Body ="";
mailObj.IsBodyHtml = true;
var smtpServer = new SmtpClient("smtp.gmail.com", 587);
smtpServer.Credentials = new NetworkCredential("marabifuad2013#gmail.com", "password");
smtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpServer.Send(mailObj);
I guess that because you haven't specified to use SSL:
smtpServer.EnableSsl = true;
Also you can try:
smtpServer.UseDefaultCredentials = true;
Apart from that everything looks fine, providing that you entering correct credentials and etc.
I am trying to send mail through mail server ( available in fatcow).
Username: info#efernssolutions.com
SMTP Server: smtp.hostname.com
SMTP Port: 587
I used the follwing code to send mail ,
if (ModelState.IsValid)
{
MailMessage message = new MailMessage();
try
{
message.To.Add(new MailAddress("kishore.eferns#gmail.com"));
message.From = new MailAddress("info#efernssolutions.com");
message.Subject = "Test mail";
message.Body = "this is the mail sended through my c#.net program";
message.BodyEncoding = System.Text.Encoding.UTF8;
message.SubjectEncoding = System.Text.Encoding.UTF8;
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.hostname.com";
System.Net.NetworkCredential nc = new System.Net.NetworkCredential("info#efernssolutions.com", "password");// is u are using Gmail
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = nc;
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate);
client.Send(message);
}
catch (Exception ex)
{
;
}
}
When i use gmail server the code works fine and i received mail.
But it is not working with my email server.
I get the error,
the remote certificate is invalid according to the validation procedure
Is there anything left to do to make it work?
Please help,

As first check I will suggest to check if your SSL certificate is correctly installed on your server
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.
