Automaticly send pdf e-mail



I found out via this forum that is is possible to have the pdf connected to an e-mail without pop-ups. There is only still 1 annoying thing.

We use this functies to send our purchase orders. We can extract these from our system, print them directly to mail and send.
However, i am forced to save them. I dont need and dont want to save the pdf, i just want is to vreate one and attach it to an e-mail.

Is there an option to save it to a temp folder which will be automaticly cleaned sometimes? We dont need the pdf, we only need to send it.
