Mail Formatting Help Needed Desperately

I've got a problem that I cannot seem to resolve... I'm sending emails from PHP4/Sendmail and the recipients are spread across Windows, Linux and Mac. It seems that the formatting of these emails are different for each, and I cannot explain why. I've done this within ColdFusion without these types of problems. the body of the message is two parts, the first of which is text I explicitly specify and then the remainder is through an HTML <TEXTAREA>. I've tried adding '\r\n' at the end of each line, and the formatting for Windows and Mac email users was fine, but the Linux users weren't getting any formatting. So then I tried just '\n' and everything was fine for Windows and Mac, but on the Linux account everything except the text from the <TEXTAREA> was formatted properly, which all ran together. So then I added a ereg_replace( "\n\, "", $text ) to the form field element, and the emails for Windows and Linux were formatted properly but the emails for Mac users all ran together. How can I format these emails so that all users (Windows, Linux, and Mac) get properly formatted emails? Formatted so that the text is properly carriage returned in the text I specify, and retains all carriage returns from the <TEXTAREA> form field. thanx! Joseph E. Sheble a.k.a.
