Here is how to setup a mailbox at Site.pro:
If you have purchased Site.pro Mail plan, you can set up your mailbox on your device or email application.
When configuring your email on your device or application, you will need to set up outgoing mail protocol (SMTP) and incoming mail protocol (choose between IMAP and POP3). If you are unsure which incoming mail protocol you should choose, refer to our FAQ article about IMAP and POP3 protocol differences.
Here are the configuration details that you will need to set up your mailbox on your device or application:
IMAP is ideal for users who access their emails from multiple devices. Since emails are stored on the server, changes made on one device are reflected across all devices. IMAP keeps your emails safe on a central server, which is helpful if your device is lost or broken because backups are available on your other devices.
POP3 is good for people who want to check their emails when they're not connected to the internet a lot. It saves emails on your device, so you can access them without internet. This is helpful in places where the internet is not always available. Also, with POP3, you have more control over how much space your emails take on the server.
