    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!

      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.

    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.

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

    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
      @7us 2 ปีที่แล้ว

      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 📧

    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
      @dougjacobson1345 6 ปีที่แล้ว

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

    • @iAmTheSquidThing
      @iAmTheSquidThing 2 ปีที่แล้ว

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

    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
      @dougjacobson1345 5 ปีที่แล้ว

      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.

      @58Galtha 2 ปีที่แล้ว

      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.

    We have local network in our company and we have mail service like "mail.company.net".. My address is user@mail.company.net
    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??

      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.
