Two Mighty Powerful Free Tools on the Web That Can Say Where You Are Headed:
Email Verification and WhoIs Domain Name Lookup

Now that we have examined methods to reveal a sender's true email address, we can use readily available free tools on the Internet to verify the legitimacy of an email address.  Simply do a search on "verify email address" to find several websites that offer the service.  We will use the Email Checker at https://email-checker.net/validate

Although the email address I entered was very long, and did not belong to actual human being, but a service I subscribe to, the email address entered was nevertheless valid.

Just supposing you wanted to email Joe Biden.  You search the web and find the email address, president@whitehouse.gov — but what gives here?  That address reports back as bad.  Turns out you can no longer email the President directly.  That email address was retired.

If you have reviewed by posting of July 7, 2022, "Anatomy of a Web Address," then you have seen examples of valid and invalid URLs.  Just because a URL is in correct format does not, however, guarantee its legitimacy.  For that we use a WhoIs domain name lookup tool.  Search "WhoIs domain lookup" and several will be listed.  For our purpose here, we will use the WhoIs lookup tool at https://www.whois.com/whois/.

Type in the URL of the website you want to check, and click SEARCH.

And we see that the website you are currently visiting does indeed exist within the ICANN domain name registration system.  In other words, eppresents.com is a real website.  If you scroll down the detailed WhoIs info, you will see the Date Created, and thus the date the domain name was registered.  A domain name created very recently is a clue that the website might not have the best intentions.

If the domain name is in correct format, but otherwise nonexistent, you might get a chance to buy the domain name.

If the domain name is in an invalid format, and therefore cannot exist, that too will reported by a WhoIs search.  Double check your typing.

The crooks responsible for email attacks like the one that plagued my client prey upon the fact that most computer users are not aware of the simple techniques outlined in these recent postings that people can use without great difficulty to thwart the actions of the various miscreants that slither across the Web.

And then you tell that Old Devil FUD, Addios, MF.
