I am sending activation and verification emails from my domain : https://www.monstermmorpg.com/
Recently I have moved to a new installation
The new server is : Windows Server 2019
How can I set a proper DKIM?
Moreover, gmail tells that the message is not encrypted
How can I encrypt messages?
I have thoroughly searched the internet and I couldn't find how to send email by SMTP when SSL is enabled
Looking for help thank you
This is my current C# code to send email
using (MailMessage Email = new MailMessage(new MailAddress("noreply@monstermmorpg.com", srFrom), new MailAddress(srEmailAddress)))
{
Email.IsBodyHtml = true;
Email.SubjectEncoding = Encoding.UTF8;
Email.BodyEncoding = Encoding.UTF8;
Email.Subject = srSubject;
Email.ReplyTo = new MailAddress("admin@monstermmorpg.com", "MonsterMMORPG Administrator");
using (AlternateView textPart = AlternateView.CreateAlternateViewFromString(srBodyText, Encoding.UTF8, "text/plain"))
{
using (AlternateView htmlPart = AlternateView.CreateAlternateViewFromString(srBodyHTML, Encoding.UTF8, "text/html"))
{
textPart.TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable;
Email.AlternateViews.Add(textPart);
htmlPart.TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable;
Email.AlternateViews.Add(htmlPart);
using (SmtpClient smtpClient = new SmtpClient("127.0.0.1", 25))
{
smtpClient.Send(Email);
return "True";
}
}
}
}
The received email source code from gmail
