Welcome to the FormMail forums! Thanks for your kind comments.
I have no idea why you'd be seeing the FormMail output as a ".att" file.* I think it might actually be your mail client (i.e. mail reader) that's doing this.* However, we've tested FormMail sending to a Microsoft Outlook Express email client and it works fine.
FormMail constructs a very simple text mail.
As a check, please configure your FormMail to send to custsupp AT tectite DOT com and then submit a form with some test data.* I can then look at the actual output to see why you're getting this behaviour.
As for the data being all jammed together, this is because the message has been turned into a ".att" file and the message contains mail-style lines (no carriage returns, just line feeds).* Windows NotePad doesn't understand these types of lines - try opening it in WordPad.
Once we get your mail server or mail client to process the mail correctly, this problem will go away.
