It appears that our Exchange Server is missinterpreting a PDF document attached to an outbound e-mail, as ?text? instead of ?binary? ? and therefore sending the message out as ?quoted-printable? instead of ?base64?. On receipt, the PDF attachment cannot be opened, as it has become corrupted. The question is ? how do we ensure that our Exchange 5.5 server always sends outbound mail as ?base64?? i.e. is there a patch to make ?base64? default?
