Oh, they do have that option, usually by default.

Outlook does, but AFAIK Thunderbird does not.

I wonder if this new malicious attachment really does have a jpg extension, or if the filename something like filename.jpg.exe.

Could be filename.jpg.exe and depending on the user default setting to not display the file extensions.

I’ve never understood that being the default. So stupid. And 25 years after we all knew it was a bad idea, it’s still the default.

Worse, Apple (Mac) does the same thing. Actually the Mac did it first and Windows just copied it. Stupid and dangerous.

I use a program called Mailwasher to preview email. I can usually tell whether an email is legit. I frequently get emails that are spoofs of my ISP. Occasionally, I get spoofs of other websites, such as Paypal.

My ISP does catch a lot of spam before it even gets to my ISP email inbox, but some slip through.
