It's not an attachment. It a subpart of an multipart/alternative message. If it was intended as an attachment, the sending email client is broken. How do you come to that conclusion looking at the source code I pasted? From the MIME structure of the message. I.e., Content-Type: multipart/alternative; boundary="===============7772187630267219476=="

How do you come to that conclusion looking at the source code I pasted? Anyway, I forgot to mention in my initial post, all other mail clients are having no problems receiving the attachement. If you take a look at the source code again, this mail is being sent to several recipients, including Google Mail and Microsoft Live accounts. All the other accounts detect the attachement and make it available for download, only mails that are sent to mail servers running horde, are having this problem.

Unfortunately I can't. There's a char limit on this field which is too low for the whole source code of the mail. Here's the header and part of the pdf.

When sending a mail with a .pdf attachment from somewhere that serves it as content-type: "application/octet-stream", the horder webmail client doesn't show the mail as having an attachment at all. But if you download the mail and take a look at the source code you can see that there's a .pdf included in the mail. Here's an example: --===============7772187630267219476== Content-Type: application/octet-stream; Name="test.pdf" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="test.pdf" JVBERi0xLjQKMSAwIG9iago8PAovVGl0bGUgKP7/KQovQ3JlYXRvciAo/v8pCi9Qcm9kdWNlciAo /v8AUQB0ACAANAAuADgALgA2KQovQ3JlYXRpb25EYXRlIChEOjIwMTcwNTAyMDUyNTQ2KQo+Pgpl bmRvYmoKMiAwIG9iago8PAovVHlwZSAvQ2F0YWxvZwovUGFnZXMgMyAwIFIKPj4KZW5k.......... --===============7772187630267219476==-- Forwarding the email to another client doesn't seem to solve the issue. At that point it doesn't seem to include the .pdf binary anymore.
