Plain text email arrives as html email

[sraman]

Hi

I was wondering if someone could help me with an issue I'm having. I'm
sending an email in plain text format with an attached file to several
email destinations. For some recipients, the email and attachement is
received ok, but for others they receive a blank email with an
attachement containing the text of the email as well as the original
attachement.

I have succesfully sent the email to aol/yahoo and some users with
Microsoft Outlook.

I have been unsuccesful in sending to some users with Microsoft
Outlook.

Regards

Salim
