Dave, When you say "I am receiving spam e-mails", what inbox is getting those emails? Is it your dave.j.moore () gmail com account?
Yes.
Do you have any forwarding set up for any email to someone () foobar net to go to that address? If info () foobar net for example is set to forward to your gmail account, than this is common - and the sender address is the easiest thing to forge.
root () avitas net forwards to me. I have not set up any other forwarders, and I have sent messages of my own to the address in question (info () avitas net) to make sure that they are not forwarding.
Making it look as if someone inside your domain is the sender is an old trick. I'd say that someone sent an email to info () foobar net where it got picked up by an internal mail server which then forwarded the mail to gmail. Adam
