Continuing with the application layer protocols, this video explores email. Mike covers the three classic email protocols: SMTP for sending and POP3 and IMAP4 for receiving. The video covers typical client configuration using the classic protocols and port numbers.
- Ooh! Email, it's been around forever. We love it, we hate it, we all use it. There was a time when we'd all have one email account and these days it seems like I've got about, I actually counted and I have around 10 active email accounts plus about another 20 barely used accounts so email is a big thing and by the way, if you ever want to contact me, here's my email address right here. Now, in order to configure email, we usually use an email client. However in today's world, web-based eamal is extremely popular. I use Gmail, I've got Office 365, I've got Yahoo. I've got Proton Mail, I've got all of these different web-based tools. However, even if you're using a web-based tool, you still have to configure it so that it can send and receive your email. Now, for a lot of folks, You fire up Gmail and you set in your account settings and boom, everything's figured. However, there are a lot of situations where you might want to connect to a non-popular one and that's really what I want to talk about here. then POP 3, which runs on Port 110, and then IMAP, which runs on Port 143. to send our mail up to an SMTP server. and all of your organization so that no matter where your client is, it will simply copy that down and today, IMAP is very, very popular. of POP and IMAP over the years. So if you see IMAP or IMAP4, it's going to be the same thing when it comes to configuration. If you're going to see POP or POP3, it's going to be the same thing because nobody uses IMAP2, for example. Nobody uses POP2 anymore, so don't panic about the number at the end of these and they always use the same port numbers no matter what. Okay, so what I want to do is I want to actually set up a more traditional email account except this time, what I'm going to do is I'm going to use my iPhone. So what I'm going to have to do is create an email account and on this phone, it actually isn't too big of a deal, but you have to know where to click so let's start setting up an email account on my iPhone. All right, so to set this up, I'm going to click on Settings and then I'm going to scroll down and find my accounts, there we go, Password and Accounts. Now what I want to do is add an account and I could use these by default which will set up all this POP and IMAP for me automatically, but we're going to do this the hard way and select Other and now I'm going to add a mail account and I'm going to give it some name and I'm going to give it some email, so I'll type in firstname.lastname@example.org. And I'm going to type in some password, total. And we're going to fire it up. So it's going to look up the account. A lot of these things would stop right here and say hey, man, there's a problem. And there really is 'cause I'm making this up as I go, but if you take a look towards the bottom here, you can see that we have a Incoming mail server and an Outgoing mail server. The Outgoing is always going to be SMTP so this particular example, I'm going to type in mail.totalhome.com and I know what to type in because somebody told me. You're not going to magically know this stuff. Now, on a lot of these SMTP servers, you have to log in with a username and password, someone would tell you if you have to type this stuff in. On the Incoming, now, this is a little bit trickier. Let me scroll towards the top and this is how they do it on this particular interface. Notice it says IMAP and POP. So if I wanted to do a POP3, I'd press on POP. If I wanted to do IMAP4, I'd press on IMAP. It's already at IMAP so we're in good shape here. So let's go ahead and type in the Incoming mail server so this'll just be mail.totalhome.com and a username and we'll probably just type in under the username, we'll just type in mike. Now a lot of times it'll look like this. .totalhome.com. Perfect. So setting up your SMTP, POP and IMAP information isn't that hard. I did it here on a smartphone. You can, laptops, desktops, anybody can do this. The trick is that you don't know this stuff auto-magically. If someone is telling you to manually set up your mail information, they're giving you this information. You've got a mail administrator who's sending you a piece of paper with his information on it. I don't magically know what this is. I don't know if you also noticed, but on the SMTP server and the IMAP, the incoming server, It's one box that's handling both incoming and outgoing. It works perfectly well. Now the one thing I need to warn you about are port numbers like 587. be aware in the real world, that these also have secure versions (light string music)
