smtpclient

i am creating simple email sending application. In my application when ever i send email i have to put my email address or password as from but i don't want to use password only want to put email so Can i send Email without using password using c#/.net application ? this is my code: try { // setup mail message MailMessage message = new MailMessage(); message.From = new MailAddress(textBox1.Text); message.To.Add(new MailAddress(textBox2.Text)); message.Subject = textBox3.Text; message.Body = richTextBox1.Text; // setup mail client SmtpClient mailClient = new SmtpClient("smtp.gmail.com");

I need to send an email as a result of a SignalR hub invocation. I don't want the send to execute synchronously, as I don't want to tie up WebSocket connections, but I would like the caller to be informed, if possible, if there were any errors. I thought I'd be able to use something like this in the hub (minus error handling and all other things that I want it to do): public class MyHub : Hub { public async Task DoSomething() { var client = new SmtpClient(); var message = new MailMessage(/* setup message here */); await client.SendMailAsync(message); } } But soon discovered that it won't work;

The SmtpClient.Send() method is throwing this exception when I try to send an email to an address containing an accentuated character (é): System.Net.Mail.SmtpException: The client or server is only configured for e-mail addresses with ASCII local-parts: léo.xxx@example.com. at System.Net.Mail.MailAddress.GetAddress(Boolean allowUnicode) at System.Net.Mail.SmtpClient.ValidateUnicodeRequirement(MailMessage...) at System.Net.Mail.SmtpClient.Send(MailMessage message) The formulation of the message makes me thing there might be a setting that I can activate to make this work, though I haven't

I'm building a web application that sends emails throw SmtpClient in .net the application is working fine, emails sent successfully to gmail accounts and hotmail accounts, however when I sent emails to yahoo account it delivered successfully, but the links I put in the message is disabled by yahoo. yahoo somehow rewrites the links and totally remove the "href" property, I dunno what to do, I've tried every format i know but it was no good. here is the code that I use to send messages. objEmail = new System.Net.Mail.MailMessage(); objEmail.To.Add(new MailAddress(contact.Value.ToString(),null));

Using SmtpClient , MailMessage and MailAddress classes, I cannot send to email addresses such as åbc.def@domain.se. I get the error/exceptions as shown below: An invalid character was found in the mail header: 'å'. --------------------------- Error sending email --------------------------- System.Net.Mail.SmtpException: The client or server is only configured for E-mail addresses with ASCII local-parts: åbc.def@domain.se. at System.Net.Mail.MailAddress.GetUser(Boolean allowUnicode) at System.Net.Mail.MailAddress.GetAddress(Boolean allowUnicode) at System.Net.Mail.MailAddress.Encode(Int32

I noticed that we always just are like: SmtpClient mSmtpClient = new SmtpClient(); // Send the mail message mSmtpClient.Send(mMailMessage); And the only place the credentials are set are in web.config: <system.net> <mailSettings> <smtp> <network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/> </smtp> </mailSettings> </system.net> So my question is, how does it automagically get them out? The documentation states that the parameterless constructor of SmtpClient reads its configuration from the application or machine configuration file. For a Web application, the application

This seems a common error but while I've found a work-around (see below) I can't pin down the reason I'm getting it in the first place. I am writing SMTP functionality into our application and I'm attempting to add SSL functionality to the working SMTP we already have. I am testing using our company's MS Exchange server and specifically the webmail option enabled on that. I can send emails internally through my code by not authenticating my connection and sending anonymously, however those emails won't relay to external email addresses due to our companies policy. Besides which I am
