HTML E-Mail Problems

[icarix]

I have written a script to mail a HTML email to registered users of a webiste using a COM object. The com object allows for me to send text and html together to allow for email clients that dont support HTML. Everything works ok and it has been tested locally in Outlook 2000, Outlook 97, Eudora 3.1 and 5.1 and web based Email such as Hotmail etc, both text and html work ok, the problem comes when I send the email to the client, they use outlook 2000 and outlook 97 and recieve neither HTML or text but a jumbled mess with a attached file of unkown origin, somewhere the mail is losing it embedded images and definitions. I have been told the client reiceves html emails from other sources so i dont think its there firewall or network that is causing the problem, can anyone shed any light on what might be causing this......... I thought there might be a setting somewhere set the mail as including html and text to inform mail servers ... or am i totally off the mark ???

thanks for your help in advance

what file extension are you sending the emails with?

not sure to be honest .. the file goes from the COM object I pass the html and the text as strings to the object, the file goes with the correct content-type and appears correctly when tested locally, the images for the html are included as embedded elements that i refer to using CID in the src attribute of IMG tags. When its recieved correctly the images appear as attached files, when it is recieved incorrectly there is only one attachment, I dont know what the file type of the attachment is when it ia recieved incorrectly ... its not a html file thou
