Update: Eine Methode, die Signatur hat sich geändert .NET 4.5, die Pausen zu oben:
Immer System.Net.E-Mail.MailMessage als ein MemoryStream-in .NET 4.5 beta

Dies ist eine sehr einfache Umsetzung mit MimeKit

using Amazon;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;
using MimeKit;
using System.IO;

namespace SendEmailWithAttachments
{
 class Program
 {
    static void Main(string[] args)
    {
        //Remember to enter your (AWSAccessKeyID, AWSSecretAccessKey) if not using and IAM User with credentials assigned to your instance and your RegionEndpoint
        using (var client = new AmazonSimpleEmailServiceClient("YourAWSAccessKeyID", "YourAWSSecretAccessKey", RegionEndpoint.USEast1))
        using (var messageStream = new MemoryStream())
        {
            var message = new MimeMessage();
            var builder = new BodyBuilder() { TextBody = "Hello World" };

            message.From.Add(new MailboxAddress("[email protected]"));
            message.To.Add(new MailboxAddress("[email protected]"));
            message.Subject = "Hello World";

            //I'm using the stream method, but you don't have to.
            using (FileStream stream = File.Open(@"Attachment1.pdf", FileMode.Open)) builder.Attachments.Add("Attachment1.pdf", stream);
            using (FileStream stream = File.Open(@"Attachment2.pdf", FileMode.Open)) builder.Attachments.Add("Attachment2.pdf", stream);

            message.Body = builder.ToMessageBody();
            message.WriteTo(messageStream);

            var request = new SendRawEmailRequest()
            {
                RawMessage = new RawMessage() { Data = messageStream }
            };

            client.SendRawEmail(request);
        }
    }
  }
}

Ich habe den code in meinem repository https://github.com/gianluis90/amazon-send-email

Ich brauche auch Hilfe, aber so weit ich gefunden habe, müssen Sie senden eine mehrteilige MIME-Nachricht mit attachment in base64 codiert.
