Yes I would love to know why this works as well. I've noticed over the past few months, I get emails that land in my gmail inbox that are obviously spam (various bs offers), and I've always wondered how they are able to bypass the spam filter with ease it seems. Also the To email line is to an email address that is a variation of my email address @aol.com that doesn't actually exist
The latest thing that started happening a week or two ago was an endless stream of unsolicited mailing list messages addressed to "Prunella" trying to get me to click on links. Ended up just setting up an autodelete when that name is in the Send field (because I discovered Gmail doesn't let you auto-spam folder things).
