I've got a client with an install of Zimbra 4.5.5 Open Source Edition. When they attach pdf's to their emails, the generated email has attachment type of text/pdf. Eg, the mime header looks like:
This causes problems when trying to open the attachment. You can't just view the attachment. I've managed to save the attachment to the hard drive and then view it, but at their site they have problems even doing this.------=_Part_2_13330996.1183002237769
Content-Type: text/pdf; name="Comparative Data.pdf"
Content-Disposition: attachment; filename="Comparative Data.pdf"
Anyone else seeing this? Any suggested fixes?
