Jason: In this lesson, we're going to talk
about mobile email configuration.
Now, most people use their smartphones and their tablets
to remain connected when they're on the go.
And one of the best ways to remain connected is by email.
For this reason, as a technician, it's really important
for you to be able to understand how to configure email
on a smartphone or tablet.
The first method to use email on your mobile device
is to simply use a webmail client.
This would include going into your web browser,
going to a website like gmail.com,
entering your username or password,
and then doing all of your email access
through that web browser.
Now, for most users, though,
this is not going to give you an optimal experience.
And instead, it is better to set up dedicated email services
on the device, using the device's email program.
In order to configure the email client on your device,
you have to understand your email server settings.
There are various methods of configuring email,
including POP3, IMAP, and SMTP.
Each of these email server types
is going to use a different port associated with it.
If you use POP3, for example,
you're going to be using port 110.
If you're using IMAP, you'll be using port 143.
And if you're using SMTP, you're going to be using port 25.
Now, these three types of servers
and the ports I just mentioned
are going to be sending the email in the clear,
which means without encryption.
This is not the most secure way of doing things.
Instead, for better security,
you should always configure SSL or TLS
when you're connecting to the email servers.
In order to encrypt your POP3 email connections,
you'll be using port 995.
If you're going to encrypt your IMAP connection,
you'll be using port 993.
And if you're encrypting your SMTP connection,
you'll be using port 465.
Also, some servers are going to require authentication,
which means you need to provide your username and password
or some other type of credentials to receive and send email.
So remember, there are multiple different ways
to send and receive email.
When it comes to receiving email,
which we call inbound mail,
you're going to be using POP3 or IMAP,
preferably with a TLS or SSL connection.
And if you're using outbound email or sending email,
you're always going to be using SMTP.
And again, we prefer to do this using TLS or SSL
to ensure there is an encrypted connection
between your mobile device and the server you're using
to send that email.
Now, if you're using a major provider like Gmail or Outlook
or Yahoo or something like that,
you're usually going to be using what's known
as auto-configuration.
With this type of a setup,
when you try to add a new email account
in the mobile client, it will simply ask,
"What is your email address?"
If you enter something like titancipher@gmail.com,
it's going to be able to recognize
that that is a Gmail account.
And because Gmail is so well known,
it already knows which POP3, IMAP, and SMTP servers to use,
and it will automatically configure that for you.
The only thing you'll have to do
is entering your email address and your password.
And that way, you can authenticate to the server
and then have the system automatically configure
all of the settings for you.
On the other hand,
if you work for a small or medium-size business
that has its own institutional email server,
these are not usually going to be set up for auto-configure.
And in these cases,
you'll manually have to configure the account
using the POP3, IMAP, or SMTP server addresses
and the ports associated with them,
as well as selecting whether or not to use encryption
using TLS or SSL for that connection.
When you're configuring a corporate email like this,
you're going to be setting up four main things.
First, the incoming mail server.
Are you going to be using IMAP or POP3 as your server?
And what is the fully qualified domain name
or IP address of that server?
For example, if you were setting one up for Dion Training,
your email server might be mail.diontraining.com.
The second thing you need to set up
is your outgoing mail server, which is going to be your SMTP
or Simple Mail Transfer Protocol server.
This is going to be used for any messages you're trying
to send out of your system.
Often, this will have the same name
as your original email server.
Or it might have something different
such as smtp.diontraining.com.
The third thing you need to set up is whether or not
to enable encryption.
This will be labeled as TLS for Transport Layer Security.
Or if you're using an older provider,
they may still be using SSL,
which stands for Secure Socket Layer.
TLS is the newer and more advanced and more secure version.
And therefore, it is what you should be using
when you're using encryption.
And then the fourth and final area you need
to configure is the ports.
Now, by default, IMAP, POP3,
and SMTP do have port numbers associated with them.
If you're using an unencrypted connection for IMAP,
that's going to be port 143.
If you're using an unencrypted port for POP3,
this is 110.
And if you're using an unencrypted port for SMTP,
this would be port 25.
Now, if you've enabled TLS with its encryption capability,
your IMAP server should be listening on port 993,
your POP3 server should be listening on port 995,
and your SMTP server should be listening on port 465.
That being said, those are the default numbers.
Your system administrators on those email servers
can actually set them up to use any port they want
as a listening port.
So you always need to check with your system administrators
to make sure you have the right email server names,
IP addresses, and port numbers
that are being used by your organization
when you're configuring a mobile device.
