[GTALUG] Anyone getting bounces from Gmail: failed sending to you@googlemail.com?

Seeing quite a few mail rejection messages:

Address not found

Your message wasn't delivered to *your.name@google.com* because the address couldn't be found, or is unable to receive mail.

<https:// support.google.com/mail/?p=NoSuchUser>

Seems there's been quite a spate of these messages where someone's trying to send from my.name@gmail.com to my.name@googlemail.com and the back-scatter does raise eyebrows. At least a couple users of Ontario LUGs are experiencing this, so thought I'd reach out. If it's wide spread, it may indicate email harvesting from the list archive.
