Send Distribution List via Email

[Andy]

Hello-

I'm trying to send a distribution list via email. Both systems are
running Outlook 2003 SP3. When I send the file I do this:
1- Start new message, change the format to rich text
2- Go to Insert, then Item. Browse to Contacts and select my
distribution list. Click OK to add as attachment.
3- Address the message and send it out.

My problem is on the receiving end. It shows up as a .msg file. Any
ideas why this is happening?

Thanks for your help,

Andy
