I've never heard of blocking .dat files. Files I block specifically based
on extension are exe,com,bat,scr,pif,vbs. This cuts out 99.9% of the
viruses. Other incoming attachments not following into one of those gets
scanning by the AV. The winmail.dat file is basically just a text file and
there should be no reason for blocking it.

Hello all,
Running Exchange 5.5
I am running GFI Mail Security and have all .dat files blocked. I am
experiencing an issue where valid e-mails from other organizations are being
blocked due to winmail.dat files being attached to their messages. It is
not realistic for me to send them directions to turn off TNEF to prevent the
winmail.dat attachment.
Do most of you block .dat files? If so, how do you overcome this issue
in your organization? I can not whitelist a specific attachment through GFI
so I am stuck.
Any ideas appreciated.
Thanks,
Chris Wall
