I am trying to send an email to admin in .NET core but it is throwing exception.

See more:

'A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond'

SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

What I have tried:

C#

public void EmailtoAdmin()
        {
            var message =  new  MimeMessage();
            message.From.Add(new MailboxAddress("my email"));
            message.To.Add(new MailboxAddress("email"));
            message.Subject = "";
            message.Body = new TextPart("plian")
            {
                Text = "abc"
            };
            using (var client =new SmtpClient())
            {
               // client.Timeout = 600000;
                client.Connect("smtp.gmail.com", 465, false);
                client.Authenticate("email", "pwd");
                client.Send(message);
                client.Disconnect(true);
               
            }
        }

google "c# send email gmail", this is one of the most frequently asked questions and all of the problems you'll encounter are already well documented.

However my advice is to not send through gmail at all, it's only going to stop working at some point.

I realize this is probably just question code, but in general, you shouldn't have "magic numbers" in the code (in this case port number)

Try this

MailMessage mail = new MailMessage();
mail.To.Add(to);
mail.From = new MailAddress(from);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp.gmail.com",587);
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential(address, password);
smtp.Send(mail);

The port is set to 587 (instead of 465).
