The question on ProWebmasters:
https://webmasters.stackexchange.com/questions/8335/what-is-the-aim-of-this-email-is-this-a-ping-sping (link to question) has been closed as off-topic. I was asking it in case someone had some background information or knowledge about spam practises.
Hi, I received this spam in my catch-all (All headers and full message in the original question).
As a webmaster of the domain it was sent to, I am really curious what the reason for this mail is. It was sent to a non-existent user "tania" on my domain - here I used mydomain.zzz - what do the sender want to achieve? Since many mail servers have stopped backscattering, not getting a bounce would not mean anything, would it?
And if this is off topic, where inb the StackExchange WOULD it be on topic?
