>>Well, First of all what is the problem:
>>You try to view in Outlook an email send with wwipstuff and Outlook reports this... or you try to send mail Automating Outlook and receive an error message.

What does outlook report?

What version of wwIpstuff are you using. THere have been a number of changes and updates in the 4.x version that deal with attachments.
