Getting SmtpClient to work with a self signed SSL certificate

半世苍凉 提交于 2019-12-01 17:13:27
I'm attempting to use the System.Net.Mail.SmtpClient class to relay an email through my company's email server. All SMTP connections to the mail server have to be SSL and it uses a self signed certificate. That's fine for Outlook where you can just click ok on the warning dialogue but does anyone know a way to get SmtpClient to accept a self signed certificate? I'm planning on using this app on the Windows Azure Platform so I won't be able to install the self signed certificate as a trusted root. You may take a look at the ServerCertificateValidationCallback property: ServicePointManager

SmtpClient get result from server on send

风格不统一 提交于 2019-12-01 15:17:42
The SmtpClient send method returns void. Is there any way to get the server response? Do I just assume it was successful unless it throws an exception? The class I'm referring to... http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.aspx To answer your second point, yes, all you can do is assume it's successful - meaning it got the message to the server and the server accepted it, unless you get an exception. You probably already know the rest of this, but just in case... From there, the email could get lost and not delivered any number of ways. Your server may accept it and

System.Net.Mail and MailMessage not Sending Messages Immediately

允我心安 提交于 2019-12-01 05:15:06
When I sent a mail using System.Net.Mail, it seems that the messages do not send immediately. They take a minute or two before reaching my inbox. Once I quit the application, all of the messages are received within seconds though. Is there some sort of mail message buffer setting that can force SmtpClient to send messages immediately? public static void SendMessage(string smtpServer, string mailFrom, string mailFromDisplayName, string[] mailTo, string[] mailCc, string subject, string body) { try { string to = mailTo != null ? string.Join(",", mailTo) : null; string cc = mailCc != null ? string

When I use SmtpClient's SendAsync to send email, how do I dispose the smtpclient instance correctly? Let's say: MailMessage mail = new System.Net.Mail.MailMessage() { Body = MailBody.ToString(), IsBodyHtml = true, From = new MailAddress(FromEmail, FromEmailTitle), Subject = MailSubject }; mail.To.Add(new MailAddress(i.Email, "")); SmtpClient sc = new SmtpClient(SmtpServerAddress); //Add SendAsyncCallback to SendCompleted sc.SendCompleted += new SendCompletedEventHandler(SendAsyncCallback); //using SmtpClient to make async send (Should I pass sc or mail into SendAsyncCallback?) sc.SendAsync
