anyone tell me what is causing this?

I typically sign my messages with S/Mime:

http://en.wikipedia.org/wiki/S/MIME

It means that not only can my message be verified by nearly every client, but messages can be easily encrypted to me as well (since the public key is included in the signature). Usually this works fine with Mailman and other mailing lists; the worst I've seen is that Sourceforge will mangle the text adding their advertisement, invalidating the signature. Other software tends to add footers as a separate MIME part.

Looking in the source of one of my previous messages, I see that the following header is set, but that the corresponding signature attachment has been stripped:

Content-Type: multipart/signed; boundary=Apple-Mail-117-728128490; micalg=sha1;
protocol="application/pkcs7-signature"

Perhaps your mail client is picking up on this header and misinterpreting it? What mail client are you using?
