Hi,

For documentation purposes I have to log (to a database) all outgoing emails exactly as they are sent to the SMTP server.
I tried using GetMessageRawData() afte the message was sent. But repeated calls returned a different result each time. And none was identical to the message-data actually being sent to the SMTP-Server.
(Among other things the order of the header-properties was changed and the the MimePart – boundary-Parameter was different each time.)

Is there a way to get the actual data that is being sent to the SMTP-Server?

Best regards,
Scotty

GetMessageRawData, if called twice, cannot return different values for each call because it simply returns the cached copy.

Anyway, GetMessageRawData returns exactly what has been passed to the SMTP server. However, if your server processes incoming messages, it can alter them after they have been submitted by MailBee. Most servers do this, at least add Received and Return-Path headers, they can also change boundary in the case of anti-virus or other checks.

Regards,
Alex

Thank you for your fast response.

I can reproduce the described behaviour every time running the following code:

Code:

static void Main(string[] args)

        {

              MailBee.Mime.MailMessage  msg = new MailBee.Mime.MailMessage();

              msg.BodyPlainText = "Testing....";

              msg.From = new EmailAddress("test1@testcenter.com", "Tester1");

              msg.To.Add(new EmailAddress("test2@testcenter.com", "Tester2"));

              msg.Attachments.Add(@"C:\LoremIpsum.doc");  // attaching 28kB Testfile

              SaveToFile( msg.GetMessageRawData(), "c:\\MessageRawData1.txt");

              SaveToFile( msg.GetMessageRawData(), "c:\\MessageRawData2.txt");

}

        static private void SaveToFile(byte[] bytes, string fileName)

        {

              FileStream fs = new FileStream(fileName, FileMode.Create, FileAccess.Write);

              fs.Write(bytes, 0, bytes.Length);

              fs.Close();

        }

After running the code MessageRawData1.txt contains:

Code:

MIME-Version: 1.0

X-Mailer: MailBee.NET 3.0.1.74

From: "Tester1" <test1@testcenter.com>

To: "Tester2" <test2@testcenter.com>

Content-Type: multipart/mixed;

      boundary="----=_NextPart_000_4 E8C_D9F719CB.AF769595"

------=_NextPart_000_4E8C_D9F719CB.AF769595

Content-Type: text/plain

Content-Transfer-Encoding: quoted-printable

------=_NextPart_000_4E8C_D9F719CB.AF769595

Content-Type: application/msword;

     name="LoremIpsum.doc"

Content-Disposition: attachment;

     filename="LoremIpsum.doc"

Content-Transfer-Encoding: base64

 0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAPgADAP7/CQAGAAAAAAAAAAAAAAAB AAAAMQAAAAAAAAAA

 EAAAMwAAAAEAAAD+////AAAAADAAAAD///////////////////////////// ////////////////

 //////////////////////////////////////////////////////////// ///////////////

[......]

MessageRawData2.txt contains:

Code:

To: "Tester2" <test2@testcenter.com>

From: "Tester1" <test1@testcenter.com>

X-Mailer: MailBee.NET 3.0.1.74

MIME-Version: 1.0

Content-Type: multipart/mixed;

      boundary="----=_NextPart_001_2 244_DE54FDA2.78DE2833"

------=_NextPart_001_2244_DE54FDA2.78DE2833

Content-Type: text/plain

Content-Transfer-Encoding: quoted-printable

Testing....

------=_NextPart_001_2244_DE54FDA2.78DE2833

Content-Type: application/msword;

     name="LoremIpsum.doc"

Content-Disposition: attachment;

     filename="LoremIpsum.doc"

Content-Transfer-Encoding: base64

 0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAPgADAP7/CQAGAAAAAAAAAAAAAAAB AAAAMQAAAAAAAAA

[...]

I also tried to actually send the message using the following code but aside from adding some header-properties (date) that didn't change anything:

Code:

              Smtp smtp = new Smtp();

              smtp.LowLevelDataSent  += new MailBee.DataTransferEventHandler(smtp_LowLevelDataSent);

              smtp.SmtpServers.Add("mail.mailserver.com");
 
              smtp.Connect();

              smtp.Message = msg;

              smtp.Send();

              smtp.Disconnect();
 
              SaveToFile( msg.GetMessageRawData(), "c:\\MessageRawData1.txt");

              SaveToFile( msg.GetMessageRawData(), "c:\\MessageRawData2.txt");

Both files contain data that differs from each other and from what is actually send to the server. (Because Servers add stuff to the header of a mail message I used the LowLevelDataSent event to check whats actually send.)

What am I doing wrong here?

Best regards, Scotty
