I thank you for your help.

I thought it might be because there's no space after Subject: in the email line, but that wasn't it. So I sat there comparing all my working scripts to this one and it finally dawned on me. I wasn't -t on sendmail.

The minute I noticed this I was 90% sure this was the problem.. sure enough, adding this to both emails fixed the problem and the emails are working just fine! I hate moving files from one server to the next, they never seem to work right away :)

Thanks for your help.
