Hello Support,

How can I remove (completely) the following sections from the "Mime"?
I've tried using "= msg.MailTransferEncodingPlain MailTransferEncoding.None" but it appears the same. Any suggestions?

Regards, Lello

Using this code:

Code:

MailMessage msg = new MailMessage();

msg.BodyPlainText = "hi";

msg.MailTransferEncodingPlain = MailTransferEncoding.None;

msg.BodyHtmlText = "hi";

msg.MailTransferEncodingHtml = MailTransferEncoding.None;

msg.SaveMessage(@"C:\Temp\test.eml");

I get this:

Code:

MIME-Version: 1.0

X-Mailer: MailBee.NET 8.0.2.440

Content-Type: multipart/alternative;

     boundary="----=_NextPart_000_E771_786ABF10.34233B2F"

------=_NextPart_000_E771_786ABF10.34233B2F

Content-Type: text/plain;

     charset="utf-8"

hi

------=_NextPart_000_E771_786ABF10.34233B2F

Content-Type: text/html;

     charset="utf-8"

hi

------=_NextPart_000_E771_786ABF10.34233B2F--

No Content-Transfer-Encoding header appears.

Please provide the complete MIME source you want to get.

I now do:

Code:

            MailMessage msg = new MailMessage();

            msg.Attachments.Add(@"test.txt");

            //Save the message

            msg.SaveMessage(@"test.eml");

            //Remove first Part from the Mime

            string boundary = "--" + msg.MimePartTree.Boundary;

            string text = File.ReadAllText(@"test.eml");

            int start = text.IndexOf(boundary);

            int length = text.IndexOf(boundary, start + 1) - start;

            text = text.Replace(text.Substring(start, length), "");

            File.WriteAllText(@"test.eml", text);

But it is not very elegant.
Alex, You know an easier way?

What exactly are you trying to achieve? Because what you get is certainly not a correct MIME source.

For instance, you get multipart with a single part inside.

I don't think it's possible to do what you want to with MailBee. And it's by design. With MailBee, you can't create incorrect MIME source (at least it's not easy, I hope).

Hello Alex,

I need to create S/MIME messages using C# (as specified in RFC 2633, "S/MIME Version 3 message specification", and RFC 3335). Are MailBee libraries good to accomplish creating S/MIME messages, and in particular, .p7s files?

Even other people ask this: http://stackoverflow.com/questions/127363/s-mime-libraries-for-net

Yes sure, S/MIME is fully supported by MailBee.NET Objects, this page is a starting point of relevant documentation.

Hello Igor,

I have to generate a "Mime" that contains only Attachments (not Plain Text, not Html Text).

Code:

MailMessage msg = new MailMessage(); 

msg.Attachments.Add(@"test.txt"); 

msg.SaveMessage(@"test.eml");

Why You input (equally) the section "Text Body"?

Code:

------=_NextPart_000_1E92_5E6E07A4.D04141E5 

Content-Type: text/plain 

Content-Transfer-Encoding: quoted-printable 

I do not want to generate this section.
How can I remove (completely) the Body sections from the "Mime"?

That approach is not supported by MailBee, body text must be there.

It's not really done that way, .p7m is not a generic attachment, and content-type there needs to be different. You need to generate the signature by signing the message, encrypting it or doing both.

Igor,

The Italian Ministry of Justice asks for a file s / mime that contains only p7m x509 signed.

After I created the file s / mime (without Plain Text, not Html Text) I have to encrypt the message with the public key x509 of the recipient.

MailBee is only capable of creating detached signatures.

The signature will be detached into a separate MIME part which will be attached to the message.

Dear Alex and Igor,

I have no problem with digital signature and encryption.
My problem is to delete the following section from the file "MIME"
Do you have any suggestions?

Code:

------=_NextPart_000_1E92_5E6E07A4.D04141E5 

Content-Type: text/plain 

Content-Transfer-Encoding: quoted-printable

I don't have any suggestions. Moreover, I don't see how deleting this section would keep the MIME structure correct.

Hello Alex,

I confirm that the Italian Ministry of Justice does not accept a MIME that contains section "Content-Transfer-Encoding: quoted-printable"

It is a MIME-encrypted and encrypted. This MIME must be attached to a normal email. This MIME must be no section "Content-Transfer-Encoding: quoted-printable" .

In that case you can use Base64 encoding. To configure the encoding, you can use the properties:

MailMessage.MailTransferEncodingHtml
MailMessage.MailTransferEncodingPlain

Hello Igor,
I set "NONE" for plain-formatted body and for HTML-formatted body but but I can not delete the section "Content-Type" (see screenshot)

========================================
// Set the NONE encoding for plain-formatted body.
msg.MailTransferEncodingPlain = MailTransferEncoding.None;

// Set the NONE encoding for HTML-formatted body.
msg.MailTransferEncodingHtml = MailTransferEncoding.None;
========================================

Hello Igor,

If I use these properties:
============================
msg.Charset = null;
msg.MailTransferEncodingPlain = MailTransferEncoding.None;
msg.MailTransferEncodingHtml = MailTransferEncoding.None;
=============================

Mime output is this:

=================================================

Is there a way to also eliminate "Boundary" and "Content-Type: text / plain"?
NOTE: I do not use this mime to send a message. I use this mime like a file container.

It's not possible. E-mails generated by MailBee cannot contain only attachment with no text body at all. All emails with attachments must bear "multipart" content type, have boundary, etc.

Alex
