Configure your email client

This document will guide you through obtaining all the details you'll need to configure most email clients. We've also included some more detail further on for those interested in knowing more!

This article assumes you using Krystal email accounts, created through your hosting cPanel. We have a guide that walks you through Adding a new cPanel email account.

We support both POP and IMAP email accounts - these are the most common protocols for receiving email. We only support secure connections (SLL/STARTTLS).

Finding all the details you'll need

  1. First and foremost you'll need your email address and password. You'll have set the password when you created the email account in cPanel.
    If you can't remember it, your only option will be to change it. You can do this by visiting cPanel > Email > Email Accounts >

    Click 'Manage' next to the email address whose password you'd like to change.

    Then type a new password, or use the Generate button.


    Click 'Update email settings' to complete the process.
    The eye icon hides or reveals the password as you type. The Generate button will create a password for you - you can click the drop-down arrow to change the password length and included characters - you will need to copy the generated password from the 'Password' field to the 'Password Again' field before clicking 'Change Password'.

  1. cPanel > Email > Email Accounts > click 'Manage' > click 'Connect Devices'

    Staying in cPanel, within the email account management screen, click the 'Connect Devices' button

    You'll then see the remaining details you'll need:
    Incoming server (usually mail.yourdomain.co.uk)
    Outgoing server (usually mail.yourdomain.co.uk)
    IMAP Port: 993
    POP3 Port: 995
    The final detail is the SMTP port. Our servers, and most modern email clients are capable of using a newer encryption (called STARTTLS) and this is served by Port 587. If your email client is older and only supports SSL then you can use Port 465.

    These are all the details you'll generally require to setup any email client.
  2. Some email clients (often those on mobile devices) don't have a specific field for the port number, so you'll need to include it along with the server name e.g. mail.example.co.uk:587 or homeserver:587 - replacing example.co.uk with your domain and homeserver with your specific hosting server e.g. hera.krystal.co.uk:587
    Sometimes you'll need to access the 'Advanced' settings to enter the port details.

More about IMAP, POP & SMTP

IMAP (Internet Mail Access Protocol) is better if you use multiple devices - each device syncs with the mail server, so you see the same emails on all devices. Email is stored on the server, with a copy synced to each device. This makes it much easier if you need to change your device - you simply connect the new email client up to the server and it'll automatically sync to the new client.

POP3 (Post Office Protocol) works by a client connecting to the server, retrieving email, and then (normally*) requesting the email be deleted from the server, there is no 'sync' as with IMAP. (* whether email gets deleted from the server or not is controlled by the email client requesting it - if the client doesn't request deletion the email will stay on the server, no matter what happens to the email on the client (read/unread/deleted). Should your client not request deletion, when a new client is connected all the previous emal will be delivered and appear unread. That email will also be taking up disk space in your account.)

We use SMTP (Simple Mail Transport Protocol) for sending email - this is an internet standard.
