Confirm that this is spam, "Messages quarantined since 2/13/2020"

I'm getting an email every night at around 4am that LOOKS like it's from cPanel, but I'm not entirely convinced so I'm hoping you guys can confirm. The email subject that it references IS one that would have been sent (but not from [email protected], and not at 3am), but the link isn't to my domain so it feels phishy.

The subject is "Messages quarantined since 2/13/2020 for [email protected]", where the date is always the previous date and the email is for my domain.

The reply email is [email protected]. I Googled this and found nothing.

This is the body, converted to plain text just in case there's something malicious in there:

[email protected] has prevented the delivery of a new message to
 [email protected] because it contains heavy attachments. To immediately release it use the "Release and Deliver" button below.

Clicking the "Release and Deliver" link takes me to:

The sender wants you to press the button Release and Deliver, I wouldn't do it.
It is spam, no doubt.

I'm positive that it's spam, though... it finally hit me to look at the source of the final link and see where the login form directed:

On the form that's an HTTP link, not HTTPS. I removed it here to prevent it from becoming a link.

It's weird that it goes through, though.

Really, anyone can implement a google api - as long as they have a google account - in case you wanted to know what firebasestorage was you can find it here: Cloud Storage | Firebase

It is spam or probably much worse. I moved from cPanel many years ago but still received an identical message to [email protected] [a domain of mine). It originated in Aruba. Very clever though. Ironically if I had still used cPanel I might have been tempted instead of instantly realising it didn't compute..

I pass my email through GMail which imho is the best spam cleaning service around - surprised they didn't catch it. Mine was received at 06:23 UTC this morning.
