Is this just another instance of spammers fishing for legit addresses? If so, then why the hell are they sending email from invalid addresses? I can dig into this a lot further if I need to, but I wanted to see if anyone else had any ideas about it first. Thanks in advance!!!
Yes (just spam -- address harvesting). There was some discussion about this exact issue yesterday over on UNISOG :
