Helper application on file type

[partypooper]

Hi!

When I try to access a .pdf file in a message (as an attachment in a message), Zimbra destkop only allows me to download it, and does not propose me to pickup an application to view it directly.

I am using Ubuntu 8.10, and everything is working fine with .doc or .xls files (gets open in openoffice directly), but not with .pdf....

Any ideas on how to fix this?

thanks,
