JPEG arrived at destination as a .dat file??

[SalesGuy]

Howdy all.

I emailed a JPEG to a number of people, using Outlook 2000 SR1 (Win 2K OS),
and the email arrived at two recipients as a file called winmail.dat. One
was a corporate email addy, the other was a Hotmail account.

Any idea's/suggestions??

Incidentaly, both recipienta have had problems wiht recieving JPEG's from us
in the past.....


TIA
