I use Firefox but wasn't aware of that feature. And it did take some effort beyond just copying the e-mail address.
But, if I did have that domain name properly registered, wouldn't Firefox discover that it was just a legitimate domain? Or could it somehow say it was close to some other domain name so, "Y'all be careful now."
1? I think if the domain name was properly registered, as an internet malefactor would probably do. So Firefox or any other internet checker would say it is OK. And then that malefactor would pass the e-mail on to the real domain that was intended so no one would suspect that the information in it, like a credit card number or information about a particular purchase etc., had been compromised.
So, I really think that if you are going to send some sensitive information via e-mail, you should use an address that was obtained by yourself from a source more reliable than an e-mail that you received that just looks legit.
I am not attacking
Daisy@jlcpcb.com or the
JLCPCB Official user ID which may be used by more than one at JLCPCB. I think it is great that they take enough interest to monitor the BB and try to answer questions or resolve problems posted here. More companies should do likewise. It is only the way that information is returned that is in question. The people who design the websites could provide the e-mail addresses to send such communications to. But instead they are more intent on reducing the e-mail traffic or eliminating it entirely.
And I am saying that they should provide real e-mail addresses, not some internet form that must be filled out THEIR WAY, often with required information you do not wish to give or with number of characters limitations.

If you are ever concerned about a potential 'look-a-like' domain, if you are a Firefox browser user there is a handy easy way you can check it: simply copy the domain part and paste it into the address bar of Firefox. It will automatically transcode any non-ASCII domains into their IDN Punycode representation and show it in that form.
For example, for the second example above, if you paste "ϳlcpcb.com" into the address bar, it will show in the suggestion box "xn--lcpcb-nle.com".
I don't know if any other browsers - e.g. Chrome, Edge, Safari, etc. - have this feature.
