Take a closer look, and I'd bet all five of those specific messages were sent through Google Groups. Number 2 and 3
I'm sure of as I've got spamples myself.
Take a broader look and I'd bet you'll find more messages with similar sender addresses, from groups whose List-ID
matches the last three (or four, looking at sample number two) domain-label parts.
Google seems to have gone out of their way to make it difficult to report Google Groups spam - or a Google Group that
was *set up for* spamming - without a Google account.
Thanks! It's been some time in which I hoped that someone at Google might read and understand abuse reports, but
apparently that isn't the case. Spam via groups continues, I've decided to block the IPs for good (it's a relatively
short list).
If someone needs those messages, they will have to use the web interface.
Cheers,
Hans-Martin
