What happens when you hit SEND on your Email? 

43 thumbs up only? It's the best video about how E-mail works i've even seen! Great thanx, Brent

Ohhh.. What a satisfying video... I liked it and didn't get bored. Very nice explanation and a soothing background music. The way of presentation is excellent. I'm gonna watch your another videos just to see the presentation.

This is the best video about this subject ever created. I watch it a lot. Thank you.

Watched this in 2023 as im in my new job in a NOC troubleshooting email servers

Very well made video! Watch a lot of them and would recommend for anyone wanting to learn what happens after you hit send to view this one!

Brent,up until today, I had no idea what happened! Hard to believe that it goes through so many steps! Thank you for sharing. I ahve to write an essay, and that is one of the questions!!

Never seen something like this in Decades, Awesome Job Brent!!! Please keep uploading and keep sharing knowledge. God Bless You :)

Great Video Brent. Please Post more Videos

This video is great! Important concepts are explained and I didn't get bored by too many technical details. If only everyone knows how to explain things this way. Thanks!

WOW!! It's a great work @Mr. Brent J Dreyer. Really helpful to understand the background mechanism of an email. Thanks.

Man something so easy is really very complicated. No wonder I didn't understand why I was having problems.

very good video ! Muy enrichissante !

It was really nice and the concept was explained in full detail. I have seen so many videos but this one is the best and easy to understand. thankyou SIR.

Hi There! Thank you so much! This was very nice presentation... the rhythm and flow were awesome. My mind was able comprehend and you've answered vital questions in fast, yet full detail. Bueno! [ I watched four other (each generating questions unanswered) ... yours was most 'complete' ! ]

Hi Sir, I am amazed while watching this video. Great and wonderful video. Thank You very much Avinash.m

Very cool Brent. Who knew!

Very nice video. I am amazed at the explanation with video. Keep working on making such video on others topic. Worlds need you man.

Really good overall in describing the general mechanics to someone who is tech illiterate, BUT: "SMTP SEVER" > ""SMPT SERVER", " DNS Dynamic Name System" > "DNS =Domain Name System" (Domain addresses are not dynamic, they are assigned, and looked up on a Domain Name Server.) and IP addresses are not 12 digit numbers. "12 digit addresses" are for IPv4 in decimal notation, which is being transitioned to IPv6. IP addresses actually are transmitted and processed as binary values, represented as either four or 6 character groups for ease of entry by humans, each being between decimal values as 000-255 for use by consumers. Techs use hexadecimal 00-ff to represent the same values. The actual numbers represented by IPv4 are between 0 and (256 x 256 x 256 x 256 -1) 4,294,967,295 or ffffffff. IPv6 was necessary because the number of assigned address hosts increased beyond 2 billion (US usage) before 1/4 of the world population had internet access, indicating that there would be more directly connected devices with addresses than people within a generation. Also "Recipients router" > "Recipient's ISP's router". That router dowsn't reassemble packets into messages, it forwards them to the email "SMTP server", SMTP being a protocol, not a service, it is frequently intergrated into the same physical box as the Recipient ISPs Mail server, which is not a POP3 or IMAP server, those also are protocols, not services. Ignored were encryption and/or tunneling at any point in the transmission process. There also was an assumption that the receipient and senders email clients were apps running on PCs, when today most email is done using web browsers, and web apps, not client side apps.

Thank you so much Brent! I really appreciate this video very useful. Email is really complicated for me but after watching this video I can now understand how it works.

This is so clear. thank you

Brent - Thanks, I'm incorporating this into my SMTP lecture.

very very thanks .very very very good video. method of explaining is fantastic.

It is very nice and easy to understand with music. Thanks, :)

man thank you very very much, bowing my head for this video.

DNS stands for domain name system and not dynamic name system. Overall the graphics give good overview

very easy understanding video sir. thanks

Amazing work sir! Thank you for the video and effort.

Good presentation. DNS should be DOMAIN Name System (@ 2:35).....:)

Excellent work. Thanks a million!

Excellent video!

excellent work...keep going BRO

easy to understand, really good video !!!

Excellent explanation! Thank you.

Excellent! Well presented and explained. Thank you!

Hi Brent, Thank you :) very much for providing such an excellent Video, It will help me a lot, and if possible, could you please publish on email header analysis. once again Thank you very much Brent. Rajesh chintala from India

This is really cool. Like it!

Great share...Thanks

Thank you so much for the video

That was Amazing way to Explain... It helped me a lot...

Nice video!

Very helpful video. Thanks.

very very nice. thanks a lot.

Nice video by the way as long as i remember recipient server is called mail exchanger, the smtp server from sender looks for MX record of recipient instead of smtp

Thanks.

Really excellent. Client has their DNS and mail server on a Virtual server and R getting "Message not delivered" "Relay access denied" (554.5.7.1) from some senders trying to email them. Maybe you could do a Sender Policy Framework (SPF) video. Thanx

Thank you

Merci.

a perfect job.

Great video. Thank you so much :)

This is a great video! Thank you for your effort. I would like to ask a question. Does every router add some information with the email? If yes how and what kind of? Thank you.

DNS = domain name server or dynamic name system?

Good video

Very very good

thank you sir this is an excellent video if you can explain to me please what is the route on powermta if you have any information i've search a lot of the meaning but i didnt found anything thank you for the video :)

hi there thank you very much!!! can you do a similar video for Web-Based Clients instead of private ? would much appreicate that since i am a beginner

nice

great video.!!! well done brent :-) and also thanks. can you please tell what is animation tool behind this ???

someone has a mailing server that is automated and the original website says on google that it no longer exists and is 'for sale'. I sent a reply to the automated address and the message bounced back undelivered. Is that why it bounced because there is no receiver? How does it work? If there's no website, can they stop sending automated emails asking me to add me to their insta? I responded with i don't have an insta account... you can add me on kofi and then it bounces back as they are trying to connect through social media and they are not even them sending, it is a robot email automation system? This tech stuff is getting ridiculous... as they are trying to build a following for ad revenue? why can't they just talk to the person old school

What about mail transfer agent?

Hi Brent. Great video! I have a question I hope you can answer. If one expected recipient of a multi recipient email doesn't receive the email and the sender doesn't get a notification of the failure of delivery to that person, do you know what the probable cause for the failure along the "delivery route" may have been which could cause the lack of notification back to the sender? The expected recipient has checked the spam and the deleted email folders on both the local machine and on the ISP's server which rules those out as the cause for lack of receipt. Thanks for any help you can be in clarifying this.

Is there anyone knows the name of the background music??

DNS=Domain Name system please correct it

dns: domain name system. Please edit

DNS -> Domain Name Server not *system

Dude you have a bad taste in music
