Hi All, I'm trying to contact my hosting company about this, but they're on a skeleton crew for holidays... so who knows when I'll get a reply. A few different email addresses on my domain are being used as the From: in a bunch of spam, starting maybe 20 minutes ago. They're not real users.. I had a catch-all address on, and started getting the hundreds of bounce messages in my inbox, which is how I knew. I know that the From: doesn't necessarily mean it came from there... but how can I definitely verify that my website isn't being used to send them somehow?
