I can't understand why this code is not working. I get an error saying property can not be assigned
MailMessage mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.To = "user#hotmail.com"; // <-- this one
mail.From = "you#yourcompany.example";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
mail.To and mail.From are readonly. Move them to the constructor.
using System.Net.Mail;
...
MailMessage mail = new MailMessage("you#yourcompany.example", "user#hotmail.com");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
This :
mail.To = "user#hotmail.com";
Should be:
mail.To.Add(new MailAddress("user#hotmail.com"));
Finally got working :)
using System.Net.Mail;
using System.Text;
...
// Command line argument must the the SMTP host.
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("user#gmail.com","password");
MailMessage mm = new MailMessage("donotreply#domain.example", "sendtomyemail#domain.example", "test", "test");
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
client.Send(mm);
sorry about poor spelling before
public static void SendMail(MailMessage Message)
{
SmtpClient client = new SmtpClient();
client.Host = "smtp.googlemail.com";
client.Port = 587;
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true;
client.Credentials = new NetworkCredential("myemail#gmail.com", "password");
client.Send(Message);
}
This is how it works for me. Hope you find it useful
MailMessage objeto_mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;
client.Host = "smtp.internal.mycompany.com";
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("user", "Password");
objeto_mail.From = new MailAddress("from#server.com");
objeto_mail.To.Add(new MailAddress("to#server.com"));
objeto_mail.Subject = "Password Recover";
objeto_mail.Body = "Message";
client.Send(objeto_mail);
First go to https://myaccount.google.com/lesssecureapps and make Allow less secure apps true.
Then use the below code. This below code will work only if your from email address is from gmail.
static void SendEmail()
{
string mailBodyhtml =
"<p>some text here</p>";
var msg = new MailMessage("from#gmail.com", "to1#gmail.com", "Hello", mailBodyhtml);
msg.To.Add("to2#gmail.com");
msg.IsBodyHtml = true;
var smtpClient = new SmtpClient("smtp.gmail.com", 587); //**if your from email address is "from#hotmail.com" then host should be "smtp.hotmail.com"**
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new NetworkCredential("from#gmail.com", "password");
smtpClient.EnableSsl = true;
smtpClient.Send(msg);
Console.WriteLine("Email Sent Successfully");
}
If you want to have your email and password not appear in your code and want your company email client server to use your windows credentials use below.
client.Credentials = CredentialCache.DefaultNetworkCredentials;

This just worked for me as of March 2017.
Started with solution from above "Finally got working :)" which didn't work at first.
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("<me>#gmail.com", "<my pw>");
MailMessage mm = new MailMessage(from_addr_text, to_addr_text, msg_subject, msg_body);
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
client.Send(mm);

Just need to try this:

int portNumber = 587;
bool enableSSL = true;
string emailFrom = "companyemail";
string password = "password";
string emailTo = "Your email";
string subject = "Hello!";
string body = "Hello, Mr.";
MailMessage mail = new MailMessage();
mail.From = new MailAddress(emailFrom);
mail.To.Add(emailTo);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
{
smtp.Credentials = new NetworkCredential(emailFrom, password);
smtp.EnableSsl = enableSSL;
smtp.Send(mail);
}
MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices.
It has more and advance features better than System.Net.Mail
Microsoft TNEF support via MimeKit.
Download nuget package from here.
See this example you can send mail
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(senderName, sender#address.com));
mailMessage.Sender = new MailboxAddress(senderName, sender#address.com);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("user#name.com", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Initialize the MailMessage with sender and reciever's email addresses. It should be something like
string from = "codeforwin#gmail.com"; //Senders email
string to = "reciever#gmail.com"; //Receiver's email
MailMessage msg = new MailMessage(from, to);

So far I have this CODE for email validation and a Mail to send Using SMTPClient However it won't work ,it won't send to the gmail stated. But i think there is no problem with my code. I need some help to make a way for sending Mail .
string validEmailPattern = #"^(?!\.)(""([^""\r\\]|\\[""\r\\])*""|"
+ #"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)"
+ #"#[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$";
Regex ex = new Regex(validEmailPattern, RegexOptions.IgnoreCase);
if (ex.IsMatch(TextBox1.Text))
{
MailMessage m = new MailMessage();
m.From = new MailAddress("kennethmontealto91#gmail.com");
m.To.Add(new MailAddress("kennethmontealto91#gmail.com"));
m.Subject = "Try";
m.Body = "TEST";
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential()
{
UserName = "kennethmontealto91#gmail.com",
Password = "********"
};
smtp.EnableSsl = true;
smtp.Send(m);
Change Your smtp.Host = "yourdomainname.com";
Try this code after **smtp.EnableSsl = true;**
string validEmailPattern = #"^(?!\.)(""([^""\r\\]|\\[""\r\\])*""|"
+ #"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)"
+ #"#[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$";
Regex ex = new Regex(validEmailPattern, RegexOptions.IgnoreCase);
if (ex.IsMatch(TextBox1.Text))
{
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential()
{
UserName = "kennethmontealto91#gmail.com",
Password = "********"
};
smtp.EnableSsl = true;
MailMessage m = new MailMessage();
m.From = new MailAddress("kennethmontealto91#gmail.com");
m.To.Add(new MailAddress("kennethmontealto91#gmail.com"));
m.Subject = "Try";
m.Body = "TEST";
smtp.Send(m);
}
This is my code :
public static void SendMail(string to, string subject, string body, string mailTitle)
{
MailMessage mail = new MailMessage();
mail.Subject = subject;
mail.From = new MailAddress("***", mailTitle);
mail.To.Add(to);
mail.Body = body;
mail.IsBodyHtml = true;
SmtpClient c = new SmtpClient("leavingstone.net", 25);
c.EnableSsl = false;
c.Credentials = new NetworkCredential("***", "***");
c.Send(mail);
}
Sometimes mails are sent, other times not - but no error is thrown.
Is it possible to fix the problem from code, or is it host fail?
Try my SMTP code, works perfect for me !
SmtpClient smtp = new SmtpClient();
smtp.Host = "mail.domain.com";
smtp.EnableSsl = Convert.ToBoolean("false");
NetworkCredential NetworkCred = new NetworkCredential();
NetworkCred.UserName = "no-reply#domain.com";
NetworkCred.Password = "**************";
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = Convert.ToInt16(25);
smtp.Send(mm);
I have bought a cPanel host and the SMTP server information is:
This is my code:
string smtpAddress = "mandane.hostcream.com";
int portNumber = 465;
bool enableSSL = true;
string emailFrom = "mahabadi#exirsec.ir";
string password = Authenitication.PassWord;
string emailTo = To.Text;
string subject = Subject.Text;
string body = Body.Text;
using (MailMessage mail = new MailMessage())
{
mail.From = new MailAddress(emailFrom);
mail.To.Add(emailTo);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
{
smtp.Credentials = new NetworkCredential(emailFrom, password);
smtp.EnableSsl = enableSSL;
smtp.Send(mail);
}
}
When I run my code and click on the send button after 1 or 2 minutes this appears:
Additional information: Failure sending mail.
What am I doing wrong?
I think you missed something, try this:
SmtpClient smtpClient = new SmtpClient();
NetworkCredential smtpCredentials = new NetworkCredential("email from","password");
MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress("email from");
MailAddress toAddress = new MailAddress("email to");
smtpClient.Host = "smpt host address";
smtpClient.Port = your_port;
smtpClient.EnableSsl = true;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = smtpCredentials;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.Timeout = 20000;
message.From = fromAddress;
message.To.Add(toAddress);
message.IsBodyHtml = false;
message.Subject = "example";
message.Body = "example";
smtpClient.Send(message);
It seems that you cannot reach Yahoo address on port 465, please check if this address reachable first because it appears to be a network issue.
MailAddress mailFrom = new MailAddress("test#smtp.com");
MailAddress mailTo = new MailAddress("tester#gmail.com");
MailMessage mail2 = new MailMessage(mailFrom, mailTo);
mail2.IsBodyHtml = true;
SmtpClient client = new SmtpClient();
client.Port = 25;
client.Host = "xxx.xx.xx.xxx"; // smtp host ip
mail2.Subject = "Testing.";
mail2.Body = "Hello";
mail2.SubjectEncoding = System.Text.Encoding.UTF8;
mail2.BodyEncoding = System.Text.Encoding.UTF8;
client.Send(mail2);
the above is my function that use to send an email via smtp, but I realized all the mail was located in my spam mail folder (Gmail). Is there anyway that can solve it ?
IsBodyHTML is marked true, but you're only providing text/html. You minimally need to include an alternate view with text
mail2.Body = "Hello";
make sure you not using Mail from and mailto is same address or
MailMessage mail2 = new MailMessage(mailFrom, mailTo);
UPDATE
mail2.IsBodyHtml = true;
SmtpClient client = new SmtpClient();
client.Port = 25;
client.Host = "xxx.xx.xx.xxx"; // smtp host ip
mail2.Subject = "Testing.";
mail2.Body = "Hello";
string html = "html";
// here is example to user AlternateViews
mail2.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, new System.Net.Mime.ContentType("text/html"));
string Plaintext ="plain text";
mail2.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(Plaintext, new System.Net.Mime.ContentType("text/plain"));
mail2.SubjectEncoding = System.Text.Encoding.UTF8;
mail2.BodyEncoding = System.Text.Encoding.UTF8;
client.Send(mail2);
Try this and revert.
