I just got a scam email about a supposed traffic fine in Portugal.

Email is obviously fake, but demanded payment of €120 by Feb 17. I've only been to Portugal once and it was in 2022, though I'm going back this April.
Email claimed to be representing ANSR, which is like the DMV in Portugal but the address is from .it domain, Italy.
Meanwhile, the only clickable page goes not to the ansr.pt site but to some other Portuguese site, where you're apparently prompted to enter your phone number. No doubt it would also ask for your bank or credit card account. I didn't enter anything.
The article says that Portugal doesn't send traffic violation notices by email, only by regular mail. Also on the ansr.pt site, there is an English FAQ and it appears the only way you can pay is by international wire, not by credit card, which is the case with some agencies in other countries, for instance, I've paid traffic fines online for France once.
In any event, for them to learn of my address and email address, the rental car company would have to be involved and if they do have to provide this information to the agencies, they will typically charge you an administrative fee.
Also official notices don't give you just a couple of days to pay.
