lately I've been getting a lot of spam where they are using my own E-mail address as the sender. The problem (of course) with going in and blocking my own E-mail address is I won't be able to send anything to other users from myself. I'm sure there has to be an easy way to block someone from coming from the Internet using my E-mail address as the sender but still allow myself to be a sender. Further I use dracd so I do need to be able to send mail as myself once authenticated from a remote mail client. Can someone tell me how to block this without blocking myself from sending E-mail on my system?
Thanks, -Troy
