Is it possible to send pdf form as attachment via server?

My client would like the user to complete PDF form in browser and send as an attachment via email.

But I am noticing that the user's email client is intended to be used (outlook, gmail, etc.), which is not reliable from a UX standpoint, and introduces possible issues. I tried it myself, with Gmail, and the document hasn't actually been received since sending an hour ago.

I read that FTF data can be sent to my server and received through a CGI script. I am guessing that this is a fairly technical process, requiring knowledge outside of my expertise, and that the PDF itself will still not be sent, rather the form data, which could then be mapped to a PDF?

Is it possible to use my web server to send the actual PDF to a recipient's email?
