Okay this one is not a "good" one, in terms of a good phishing email, because it is obviosly a phishing email since I do not have the mentioned product bought at mentioned company. But the fact that I get constantly emailed these made me finally post this to the website.

I get them mostly in a pair of two, one to my main domain and one to a subdomain (which includes the term noreply as part of the domainname).

Why is this email invalid?

First of all, the sending host is not a Netcup GmbH server, it's hostname is v2202311112809242991.luckysrv.de. This makes the mail suspicious, but the main criteria why this email is no valid in no way: my domain oe7drt.com is not managed at Netcup at all. There is just an A and AAAA (and others) record that points to a root server at Netcup.

I thought I might share this one as well, because I get about 6-8 emails per day about my "netcup domain". The fun thing is, one of the domain has a noreply in the domain name; I use this for several git repositories (like Github does). And to eliminate any kind of misinterpretation: the domain includes noreply -- not nodeliver.
