+Vasiliy Tikhomirov Thank you for your kind remarks. I have been doing this for a long time and it still amazes me what happens in a split second.
Never seen something like this in Decades, Awesome Job Brent!!! Please keep uploading and keep sharing knowledge. God Bless You :)
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.
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.
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!
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.
Hi There!

Thank you for the compliment.
Thank you so much for the video
Very helpful video. Thanks.
Very cool Brent. Who knew!
Brent - Thanks, I'm incorporating this into my SMTP lecture.
+Bill Richards. That's great Bill. I'm glad that you found my video helpful. Brent
It would be good for an introductory lecture which had the primary purpose of showing that the process is complex.
It's the kind of thing I'd use to contest a compliant about reliability of email as "a simple system that everyone understands".
But there are so many detail errors and omissions that I would not use it to teach how SMTP works. SMTP is a protocol, and processed like every other internet protocol. Multiple servers providing routing services are a distraction.
SMTPs part of the process can be easily and better explained by first eliminating all but the classic communication channel model components:
Sender, encoding, decoding, recipient are two mail hostss(servers) processing one message. The first email communications were host to host, with the client and mail service on one device at each end.
Great video. Thank you so much :)
I'm glad that you liked it. Thank you for taking the time to compliment.
Excellent video!
thank you for the compliment !
excellent work...keep going BRO
very easy understanding video sir. thanks

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.

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.
very very nice. thanks a lot.
Thank you for taking the time to let me know that you liked it. :)
a perfect job.
Watched this in 2023 as im in my new job in a NOC troubleshooting email servers
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
Hi Muhammad, thank you for the compliment and the clarification. Best Regards, Brent
Nice video!
thank you for the compliment
Thank you
You are welcome. Thank you for taking the time to comment. :)
Man something so easy is really very complicated. No wonder I didn't understand why I was having problems.
Thanks.
Great share...Thanks
Brilliant, educational, and fun!
I have to say that was very interesting to watch. Made me exhausted just watching it.
Good presentation. DNS should be DOMAIN Name System (@ 2:35).....:)
Good video
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.
DNS stands for domain name system and not dynamic name system. Overall the graphics give good overview
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
great video.!!! well done brent :-) and also thanks. can you please tell what is animation tool behind this ???
Thank you for the nice comment. I used VideoScribe.
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 :)
Merci.
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.
+SandandSea4me, thank you for the comment.
With regard to your question, there are dozen of reasons why this could happen. Many times, an ISP will reject and email and send no notification to the sender. That could be caused by specific content, the sending ESP, the specific date and time that the ISP received it... and so on. It could also be that the recipient hit the SPAM or JUNK button in the recent past, which triggers a feedback loop for most ISPs. In that case, the recipients IP will not receive email from that sender, ever again.
To help you understand these complexities, take a look a the infographic that I posted to illustrate the factors of email deliverability.

Thanks again for the compliment. Brent
Very very good
+Andrew Ryan - Hi Andrew. Thank you for taking the time to post a nice compliment.
Brent J Dreyer Oh you welcome, Thank You!!
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
DNS = domain name server or dynamic name system?
+Neha Jadhav . Hello Neha. I agree, Dynamic Name System is confusing. It should be Domain Name System, which is often referred to as the Domain Name Server because the System has to run the on the Server hardware. Thank you for your comment.
Your video is very useful. I understood the whole process within fraction of seconds. Thank you so much for this video.
+Neha Jadhav Thank you for the compliment. It is easy to make something hard to understand (I see that a lot), but it is hard to make something easy to understand.
Neither. DNS is Domain Name System. A server that provides the lookup and replies with an address is a domain name system server.
Domain Name System
nice
Is there anyone knows the name of the background music??
What about mail transfer agent?
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
DNS=Domain Name system please correct it
dns: domain name system. Please edit
DNS -> Domain Name Server
not *system
Thanks for your comment Kayvoh. Originally, that is what I had, but two of our senior network techs suggested that I change it to 'system'.
The system is the one that interconnects the whole internet but what holds the whole system together as a unit is called the Server, its a computer
