Hi Randy,
SmarterTrack does not make any changes to the attachments that come in on a ticket. It will simply attach what it was given from the email. The winmail.dat file is coming from the sender, and I believe a simple configuration change within your client's Outlook application is all that's needed to fix this issue.
Thanks,
