Thank you, Pete.

Just make sure to read notes 3 and 4 in Petes link.
Catch all gets increasingly common, for spam reasons. To lower the value of spamming lists, and also to make it easier to find spammers.
Which brings us to note four, the most common reason to do this check is to keep your spamming lists updated, it's by some companies considered to be one of the more reliable spammer indicators.
Overuse it and you're blacklisted.

Of course... Because all mail servers left port 25 open for insecure telnet communication...

Alex: Fix it? How you gonna fix this?

How would a mail server know if there is another mail server or a telnet client in the other end?

Many mail servers don't give an immediate error these days as an anti-spam measure and to prevent bots from brute-forcing out a list of valid users.

No. Actually... this is absolutely possible if the mail server software follows the smtp protocol specification.
Showing my age here... but for many years I used telnet to connect to my e-mail provider to send/receive mail. You can still do it... try it.
In the old days you could telnet into a smtp mail server at port 25 and do:
RCPT TO:<some.address@somewhere.net>
To which the mail server would immediately respond:
550 No such user
This is still the latest standard smtp protocol as described in RFC 5321 section 3.3[^]

That was linked too. It's useless, but I guess it depends on your definition of "verify". An account existing doesn't mean it's the right address, it could still be mistyped, misremembered, or especially intentionally wrong because it does literally nothing to stop that. It doesn't even mean it actually exists, it could be one of those 1-minute temporary inboxes. It would catch some typos I suppose.
I would definitely not consider the address "verified" after this. "Verified for spam purposes" perhaps.

(Because, as everyone knows, there is a top and a bottom.)
And if anyone has ever been so crazy as to try such a thing, please report: did it still taste as good?

I concur!
Kudos for pointing that out so well!

Why, thank you.
This[^] may be considerably hard for a number of people to envision (there's no up or down, duh. It's a spheroid for God's sake).
But if understood, it could possibly open up ones mind to observe the Earth's trajectory and spin from different perspectives.

I often do this as some hamburgers are a little drippy and the top bun is better at absorbing the drips before they drip on you! Also, sometimes by the time you unwrap a take-out burger the bottom bun has become soaked and soggy so flipping it upside down provides a more robust "plate".

24 points for getting the word "robust" into a workable sentence, that has nothing to do with software development.

Wow! Thanks. I now have a total of 24 points. I wonder what to do with them...

Robust is the word I usually use in connection with people who appear to be of a simple personality disposition. Some even feel honored.
The language is JavaScript. that of Mordor, which I will not utter here
This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a f***ing golf cart.
"I don't know, extraterrestrial?"
"You mean like from space?"
"No, from Canada."
If software development were a circus, we would all be the clowns.

I'm more curious how you'd get "robust" into a sentence about software development while keeping a straight face.

A robust and scalable architecture.
The word is overused everywhere in software development.
