Lesson 13: How Email Works

Describes the paths that emails follow across the Internet.

[@alittax]

What I especially like about this presentation is that everything is on a single slide, and you're pointing out things with a blue rectangle or dot as you're explaining it. Well done!

[@fcortesjp]

best 10min spent on the web today!. thank you

[@anacod9114]

Cheers for this, I have been researching "email marketing for mobile devices" for a while now, and I think this has helped. Have you ever come across - Jenevi Digital Duppy - (just google it ) ? Ive heard some decent things about it and my m8 got great results with it.

[@WeekendMuse]

Informative video. It would be helpful to see an example of a forged email and how to spot them in the headers.

[@mferreira1231]

This was such a clear explanantion, insane. Thank you so much

[@kso35]

love these videos. very helpful!

[@casual_sky2]

This is perfect! Thanks for the basic introduction

[@sreeragnair4472]

Nice and clear.

[@gotechakash]

So Good 👍 thanks a lot man 👏 the way you explained was so good!

[@Raquistis]

very clear and concise, good job

[@PiazzaIII]

Amazing content! Simple and easy to understand!

[@devingu5554]

The BEST email explanation ever

[@justindawson55]

Brilliant explanation.

[@valikr7062]

Simplified: the @ in the UA Header is a DOMAIN, witch is forwarded to a DNS server to translate into IP-Adress.

[@gotechakash]

This video is being really very helpful for me in my unified communication training thank you so much for this one, really a very good great one. Thanks again. ONE SUGGESTION - please don't keep similar type rhyming names while explaining. Alice & Bob was better than Jan and Jill because these two Jan & Jill rhyme together so well, that's why I was getting confused in between of your explanation.

[@deepaksonu999]

thank you for making such informational video

[@muhammadhakim6038]

Nice explanation :)...alhamdulilah

[@argenisaguilar9045]

Great...thanks so much..

[@JimTaylor42]

I'm confused. On the Account settings in my Thunderbird client, it shows my outgoing server is SMTP, but the Server Type is IMAP. I have been having trouble with my email connection failing and wonder if this could have something to do with it.

[@dougjacobson1345]

In Thunderbird, the server type is IMAP, your outgoing server is specified in the account setting

[@iAmTheSquidThing]

SMTP is used to send email. IMAP is used to check and receive it.

[@namancomtech]

Amazing information

[@RAHULNAIK03]

How does sender MTA comes to know about recipient MTA? How does sender identify correct destination MTA while delivering mail from A party to B party?

[@7us]

It'll send DNS query to the recipient domain (the one after "@"), and ask for the MX record. That where it will send the e-mail 📧

[@cedricjoshdantes3021]

Thank you.

[@rairoshan7635]

Now thats how you explain how email works

[@Ethgurl]

Can you further explain why it has to go through 3 MTAs from Application-based UA and 4 MTAs the other way around ? Thank you

[@dougjacobson1345]

It is only going through 2 MTAs in this figure. The email is created by Alice on her UA (like outlook) and the UA sends the message to an MTA, which forwards to the destination MTA. Bob's UA then pulls the email from the MTA. It is possible that there could be more MTAs along the route depending on the path the email takes.

[@Ethgurl]

@@dougjacobson1345 I meant the first example Jack and Jill. Thanks

[@dougjacobson1345]

@@Ethgurl The figure shows going through 3 each way. The confusion might be in the web based UA. In a web based UA there is the connection across the Internet between Jill and the UA.

[@58Galtha]

Wonder if the email systems default to another server if the first one is too busy or temporarily out of service? Perhaps that is why it is possible that the email might take another path? We tend to assume that everything will work as planned each time we send an email. But, realistically, we know that computers can have glitches and need to be rebooted often to keep the systems working correctly. Alternate paths are a possible solution to that reality.

[@rohitmanoharan7313]

Thankyou so much

[@karenbarnes5982]

I did not know there was a private email system.

We have local network in our company and we have mail service like "mail.company.net".. My address is [e-mail] I can access these using browsers bu i am unable to set up outlook and thunderbird... What information do i need to set up Thunderbird? I tried solutions mentioned online but those didn't help. As i am able to use browser to access mails, can i retrieve some information using wireshark, while accessing mails that i can use to setup thunderbird??

[@IowaCyber]

Could be your company does not support remote access via TB or Outlook. Can you use them inside your company (while your at work)? If so then maybe going in through your VPN. If not then they are going to have to enable SMTP access for sending and IMAP or POP for reading.

[@santhoshwagle9857]

@@IowaCyberdon't browsers use SMTP/IMAP protocols for sending and receiving mails?? i assumed TB is just another email client. "if i can access mails from browser, i should be able to access it through TB" correct me if i am wrong. dont all email servers support TB or outlook?? how is accessing mails from TB different from accessing it through browsers??

[@IowaCyber]

@@santhoshwagle9857 your browser will use HTTP / HTTPS to communicate with the system running the email server. That system is running a web server with software that enables the web server to communicate with with the email system (SMTP & POP/IMAP).
