For the past weeks I've been receiving emails that are pretty obviously spam. Here's one I just got:
sender: Динасий Колпаков <kolpakovdinasij@gmail.com>
subject: Q7425 7235 F0 8741
(empty body)
They all have similar formats, with a .htm attached file with ridiculous names like "Elon secret invitation" or "how to get free bitcoin".
They are all look like 90's era spam. Yet not only aren't they caught in the spam filter, they arrive to my main inbox, they aren't even classified as promotions or anything.
I can also see a long CC list, since it's not hidden.
Are any of you also having a similar problem?
