This article assumes that you have already configured a mailbox using a Krystal cPanel account. To carry out the instructions in this article you will need the Manual Settings for your mailbox. You can obtain these in cPanel > Email Accounts by clicking on the More button next to your mailbox details, and selecting Configure Email Client.
There are now two options for setting up your email client. Option 1 is preferred, but does have some prerequisites.
Option 1 - Use mail.your.domain for inbound and outbound mail server (IMAP Hostname and SMTP Hostname)
Your domain’s A record must be pointing to your Krystal hosting server. If your domain is registered with Krystal then this is likely the case.
You must have SSL enabled for the domain. Once your domain is correctly pointing to Krystal a free LetsEncrypt certificate will be issued automatically.
If you meet these requirements then you can use the format mail.your.domain for the inbound (IMAP Hostname) and outbound (SMTP Hostname) mail servers in the instructions below e.g. if your domain is example.co.uk then you would use mail.example.co.uk as the inbound and outbound mail server names.
This option has the benefit of meaning that should you change hosting servers at any point you won’t need to re-configure any email clients. Once the DNS has updated for your new server A record the clients will continue to be able to send and receive email.
Option 2 - use the server hostname for inbound and outbound mail server
This option has no prerequisites. However, you should be aware that if you use this method, and at a later date change hosting servers you will need to re-configure any email clients.
If you are a reseller this would also impact all your client accounts.
Start the Mail application from the Dock, or by opening it from the Applications folder.
If you have not yet configured Mail, then skip to Step 3. If you already have one or more email accounts configured in mail.app then you must first access the Preferences. You can do this by pressing Cmd- or by clicking on the Mail menu item and choosing Preferences.
Once you see the Preferences pane as below, then click on the Accounts button. Then, click the + button.
This will present you with the Welcome to Mail (if this is the first time you have started Mail) or Add Account dialog box (they both look the same)
You will almost certainly see the following warning message. This is simply because Mail tried to guess your mail server name and got it wrong.
Regardless, click Connect - we will correct this in the following steps.
Step 5 - Incoming mail settings
Choose if you want to access your mailbox using POP3 or IMAP from the Acount Type dropdown control. IMAP is better if you want to access your mailbox from multiple devices. POP3 is better if you want to use a little space as possible in your hosting account.
Step 6 - Outgoing mail settings
That's it! If you have managed to type everything in without error, then you should see the Account Summary as below. Make sure the Take account online checkbox is ticked, and click Create.
There is usually no need to change any of the default settings in Mail.
Step 8 - Recommended settings
While the above settings will bet you connected, please read the following, as it will help you to get the most from Mail
a.) POP3 Collection interval
If you are using POP3 to collect email, then it is important to ensure that you don't collect your email too often, or you may get blocked from the server for a while. Open Mail's Preferences as in Step 2, above. We recommend you leave your Check for new messages interval set at Every 5 minutes to avoid this. See below.
b.) Recommended IMAP Mailbox Behavior
We recommend these settings for the best experience if using IMAP.
c.) Assigning the proper Mail functions to IMAP folders
Mail can display your Drafts, Sent, Trash and Junk folders in a more pleasing and integrated manner if you can tell it which IMAP folders on the server carry out these functions. You do this by highlighting each of the folders under your Krystal email account, one at a time, and then selecting Use This Mailbox For... from the Mailbox menu in Mail.
For example, to assign the Sent folder in your Krystal mailbox as a folder containing sent items, firstly click on the Sent folder once as below.
Then select Use This Mailbox For > Sent from the Mailbox menu, as below
Once you have done this, your Krystal mailbox sent items will appear under Mail's unified Sent folder as below. This is useful because if you have multiple mail accounts, then this practice allows you to view all of your Sent (or Draft, Trash and Junk) items from all of your mail accounts in one place. Repeat the process for the Junk, Trash and Draft folders.
