I run a mail server for my company with Ubuntu 10.04 LTS and postfix

attachments of our messages with *special chars* to
"randombogusfilename.dat" (_not_ winmail.dat!). Their support
directed me to this Symantec KB which, in short, says "it's not our
fault", even though they are the only destination where I have
noticed this:

Has anyone experienced this or know what's this about and how to
fix/workaround this? Searched Google but no luck.

If you're paying for Symantec support, by all means open a trouble
ticket and force some cooperation for your dollars.
My customer is. Customers are always rigth, by definition. ;) They are
researching on their side (I hope) with Symantec. But they are not yet
entirely convinced it's their fault, as the KB above says.
A good start would be full message decodes on both sides (the raw
message both on the client and in the mailbox), as well as packet
dumps on both ends, to see how the message was altered in transit (if
it was.)
It is. If I mail an attachment to my boss and cc my customer, my boss
gets it correctly but my customer get a .dat attach. Only this customer.
A tcpdump comparison between the client-side and the mailbox-side
would show if Symantec is correct in that their
mail-gateway-software-money-making-machine does not alter the message
in transit, or if it does.
Your and all experience: is there how to workaround (and thus giving my
customer a hint on how to fix) this behavior of SMG? Will fuzz with
message encoding on Thunderbird and test what happens, but rather not
reinvent the wheel.
Thank you all, best regards.
