You can submit to a server-side script, which you have full control over
the message and can customize the attachment the way you need such as
file name or message body, and send a message response or redirect the
user if the message has been sent or not. Using a server-side script
bypasses Client Side Email software, so it can work for everyone who
opens and submits the form, regardless of whether they have Outlook,
Lotus, or a web based e-mail client.Sounds like PDFEmail.net would work
for you...
