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).

{{< alert >}} Update on Nov 18 2023: I'm sorry, this is either a very dumb person (or group) or it is a very funny coincidence. I got two new mails today in which the shown URL was changed to www.customercontrolpanel.de, the link still goes to the italian site (that you will find further down in this article). {{< /alert >}}

Following only the relevant part is shown.

{{< alert "bug" >}} Please ignore the 📅 signs in the sourcecode above, the content ist "emojified" and I have currently no idea how to turn this off... {{< /alert >}}

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.

{{< alert >}} Update on Nov 18 2023: Oh, just because I updated the new URL they present you: they also send from a new hostname: v2202311110463243091.nicesrv.de -- well, both domains are saved on Netcup DNS servers which may indicate something ;-) {{< /alert >}}

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.

Quite a few huh?
