[Zope] dtml-sendmail error with pine

Hello, this email is sent from a dtml document, with the dtml-sendmail tag. I have followed the instructions in the zope book and some examples in this mail list, but the viewing of attached file doesn't work with my pine email client !! It works well with kmail, but no with pine, so I suppose that the format of the message is not 100% correct. Attached is a pdf document.
