I made a console application to test MimeKit, it's executed without errors but emails never arrives.
i usae same data with System.Net.Mail and all works fine.
What can be the problem?
MimeKit code:
var email = new MimeMessage();
email.Sender = MailboxAddress.Parse("aa#sbb.com");
email.To.Add(MailboxAddress.Parse("aa.cc#dd.com"));
email.To.Add(MailboxAddress.Parse("bb.dd#dd.com"));
email.Subject = "test";
var builder = new BodyBuilder();
builder.HtmlBody = "corpo";
email.Body = builder.ToMessageBody();
using var smtp = new SmtpClient();
smtp.Connect("smtp.xxx.com", 25, SecureSocketOptions.None);
smtp.Authenticate("ut", "pwd");
smtp.SendAsync(email);
smtp.Disconnect(true);
Console.WriteLine("Email Sent.");
System.mail code:
using (MailMessage mm = new MailMessage())
{
mm.To.Add(new MailAddress("aa.cc#dd.com"));
mm.To.Add(new MailAddress("bb.dd#dd.com"));
mm.From = new MailAddress("aa#sbb.com", "You");
mm.ReplyToList.Add("aa#sbb.com");
mm.Subject = "vecchia mail";
mm.Body = "con system.mail";
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.xxx.com";
smtp.EnableSsl = false;
smtp.UseDefaultCredentials = false;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
NetworkCredential NetworkCred = new NetworkCredential("ut", "pwd");
smtp.Credentials = NetworkCred;
smtp.Port = 25;
Console.WriteLine("Sending Email......");
smtp.Send(mm);
Console.WriteLine("Email Sent.");
}
Thanks to #Klaus Gütter i got the error and then find the solution: a security rule that prevent connection between development machine and mail server, once deployed the application in test environment all works fine.
thanks for suggestions

I am getting Time-out Error.
I am not able to send email using this code. I tried almost every
possible way but of no use.
try
{
string myString = "Hello I am new email message. I am delivered for testing.";
MailMessage mm = new MailMessage("XXXXXXXXXX", "XXXXXXXXXX");
//mm.CC.Add("XXXXXXXXXX");
mm.Subject = "Subject have been successfully placed.";
mm.Body = myString.ToString();
mm.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential();
NetworkCred.UserName = "XXXXXXXXXX";
NetworkCred.Password = "XXXXXXXXXX";
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 465;
smtp.Send(mm);
Request.Cookies.Clear();
}
catch (Exception ee)
{
Response.Write(ee.Message);
}
try this
private void SendMail()
{
MailMessage mail = new MailMessage();
SmtpClient mailClient = new SmtpClient("smtp.gmail.com", 587);
mail.From = new MailAddress("Setfromaddress");
mail.To.Add(new MailAddress("recepient#gmail.com"));
mail.Subject = "Test";
mail.Body = "This is a test";
mailClient.EnableSsl = true;
mailClient.Credentials = new NetworkCredential("Username", "Password");
try
{
mailClient.Send(mail);
}
catch(Exception ex)
{
WriteErrorOutput(ex.Message);
}
}
also I think we need to check the connection
To run the telnet and test on a Windows in your computer:
1.Open the Start menu, and select Run.
2.Enter command in the Open: field, and click OK.
3.Enter 'telnet smtp.gmail.com 465,' and hit Enter, or enter 'telnet smtp.gmail.com 587' instead.
I am trying to send an email to Multiple email addresses. But I am getting this exception
A recipient must be specified
at this line
smtp.Send(mail);
I have checked related posts on stackoverflow then
I have tried to add this line
mail.To.Add(new MailAddress(c[0].Address));
but this time exception message says
: Mailbox unavailable. The server response was: 5.7.3 Requested action aborted; user not authenticated
This is my code:
MailMessage mail = new MailMessage();
mail.From = new MailAddress(emailFrom);
MailAddressCollection c = new MailAddressCollection();
c.Add(new MailAddress("sendto#gmail.com"));
mail.Subject = "some word";
mail.Body = "some word";
mail.IsBodyHtml = true;
if (c[0].Address.Contains("yahoo"))
{
using (SmtpClient smtp = new SmtpClient())
{
smtp.Credentials = new NetworkCredential(emailFrom,PASS);
smtp.EnableSsl = true;
smtp.Send(mail);
}
}
else if (c[0].Address.Contains("hotmail"))
{
using (SmtpClient smtp = new SmtpClient())
{
smtp.Port = 587;
smtp.Host = "smtp.live.com";
smtp.Credentials = new NetworkCredential(emailFrom, PASS);
smtp.EnableSsl = true;
smtp.Send(mail);
}
}
else if (c[0].Address.Contains("gmail"))
{
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new NetworkCredential(emailFrom,PASS)
smtp.EnableSsl = true;
smtp.Send(mail);

I am trying to send mail using gmail in asp.net
My Code:
using (MailMessage mm = new MailMessage(txtEmail.Text, txtTo.Text))
{
mm.Subject = txtSubject.Text;
mm.Body = txtBody.Text;
if (fuAttachment.HasFile)
{
string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);
mm.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
}
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
ClientScript.RegisterStartupScript(GetType(), "alert", "alert('Email sent.');", true);
}
But i am getting error:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at
where is my error?
You can try the below suggestions:
Try setting "UseDefaultCredentials" to "False" smtp.UseDefaultCredentials = false;
Try logging to your Gmail account, it may be blocking the access.
Try enabling access to your Gmail account, see this link for more information http://email.about.com/od/gmailtips/qt/How-To-Unlock-Gmail-For-A-New-Email-Program-Or-Service.htm
Change "smtp.UseDefaultCredentials = true;" to "smtp.UseDefaultCredentials = false;". Or test your gmail account with code below.
using (MailMessage mm = new MailMessage(new MailAddress("sender#example.com"), new MailAddress("recipient#example.com")))
{
mm.Subject = "test";
mm.Body = "body test";
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
NetworkCredential NetworkCred = new NetworkCredential("sender#example.com", "password");
smtp.UseDefaultCredentials = false;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
}
UPDATE
Go to: google.com/settings/security?hl=en_GB and if field "Access for less secure apps" is Disabled click settings and change it to enabled... Then test your connection with code above. It worked for me on new gmail user
