For what it's worth, I get the EXACT same format of spam, and I am also on Fastmail. It's a minor nuisance. One day I will write a sieve filter to try to catch them, because basically nobody sends invoices that look anything like this. But, no two of them really look the same...

Thank you. I now will not consider switching to Fastmail.

Also, I don’t trust Australia on encryption.

Scrolling from the top to this point in comments, Australia+encryption was mentioned 5 times already, and refuted every time... My take: if you want encrypted email, encrypt it yourself. It's less convenient, but at least you know it a) works; and b) will continue to work no matter the jurisdiction and your relationship with the authorities.
