VBA Lotus Notes attachment wont send when using both Richtext and MIME-CodePudding

I have code that essentially sends an email, it creates the email with a MIME HTML body and a Richtext PDF attachment. The weird part is, is that when the message is saved, both the HTML Body is there and the attachment at the top are both present.

When I send this out externally the PDF attachment is no longer there. If I comment out the HTML MIME part of the code the attachment sends attached at the top externally just fine.

Why is one preventing the other and how would I get both to send the same way the document is saved?

Any help would be appreciated.

Document now attaches as PDF below the HTML body but is blank.

CodePudding user response：

An email message can either be built with Notes Rich Text or with MIME. It can't be built with both.

If you want to send both, you will have to construct a multipart/mixed message (a parent NotesMIME entity with multipart/mixed for the content-type, like you have above, but it needs to have two child NotesMIMEEntity parts. One child NotesMIMEEntity will be for the text/HTML content -- it will need its own content-type set to text/html. The second child NotesMIMEEntity will be for the attachment. You will have to read the attachment data from the file and encode it as base64. You can find a LotusScript function that does base64 encoding here. Then you will set the content of the child entity from the base64 data, and set the headers for this with appropriate info for the file. E.g., if it is a PDF you are going to want MIME headers that look something like this:

Content-Type: application/pdf; name="MyPDFFile.pdf"
Content-Disposition: attachment; filename="MyPDFFile.pdf"
Content-Transfer-Encoding: base64

For most other file types, I think application/octet-stream is what you will want, but it's been a while and there could be other type/subtype combinations available. Whenever I have any questions about what MIME headers should look like, I manually send an email to my gmail account containing an example of the content that I want and use the 'show original' feature to examine the tree structure and details of the headers.
