Cant open pdf attachment

[razalas]

Am sending e-mail with pdf attachment from Linux RHEL to corporate e-mail server (Kerio Connect 7.1), which is delivered to user desktops who are using Outlook 2003 mail client, but we can't successfully open the pdf attachment from Outlook 2003 mail client. When we attempt to open the pdf, we get the following message from Adobe Reader (v 8.2.5):

"Adobe Reader could not open 'AR-0033GOLDM4522860101.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."

However, same e-mail with attachment copied to external mail (gmail) does allow attachment to be opened successfully from within gmail. I am fantasizing that this is simply a case of needing to "tweak" the headers to get Outlook to cooperate. Anybody got any suggestions?

Email headers, as fed directly to sendmail, follow:

first thing i would do is update reader on the machines receiving the pdf.

if the pdf is sent to gmail, opens/displays fine and is then fwd to corporate email, what occurs? still unable to display?

what is being used to generate the pdf file?

I can open the pdf just fine if I deliver it to my desktop via ftp. So, I believe the issue is not the version of Adobe Reader, but rather something that's happening in the transport or handling of the attachment when delivered via the mail system.

If we forward the e-mail from the gmail account (where we can open the pdf) back in-house, we still cannot open it.

I am thinking the next tree I need to bark up is Kerio Connect, although I searched their knowledgebase and didn't find what I was hoping for.

Figured it out. Removed the "begin" header (see highlighted in example below) created by the uuencoding of the pdf attachment data. Now it works ok.
