A little while ago, my computer got hacked (I think) and someone sent me an email to my gmail account. It was from the email address of one of my own domain names firstname.lastname@example.org and when it was inspected, my hosting company told me that the email was actually sent from my own computer to my gmail. I have no idea how they did this, but I assume that it means that I can do it as well (if only I know how)
This is the information in the header of the email that I received from my own computer (except that I've removed myname)
Can you tell me how I can send an email from my computer using the info below?
