- When you purchase a cloud server or email domain service, the system assigns a bound IP address to that server. Since IP addresses are made up of numbers and are hard to remember, domain names are used instead. For example, mail.com corresponds to an IP address. Domain name resolution points a domain name to a website IP address, allowing users to access your website or send email to your mailbox through that domain name.
- An A record points to an IP address. For example, a server has an IP address, but users are unlikely to access it directly through the IP address, or multiple websites may be bound to the same IP address. In this case, you can point the domain name's A record to the IP address to enable access to the website.
- A records are used for website resolution, while MX records are used for email resolution.
- SMTP is an email transfer protocol, generally used for sending and receiving email.

- IMAP is an interactive protocol that allows users to read email content.

- A domain name, also known as an internet domain, is the name of a computer or group of computers on the Internet, composed of a series of names separated by dots. It is used to identify and locate computers during data transmission.
- Example: mail.com
- Domain names are generally purchased on platforms such as GoDaddy and Cloudflare.
- A primary domain is also called a main domain or root domain.
- Example: mail.com
- Primary domain: mail.com, corresponding email address: [email protected]
- Second-level domain: sub.mail.com, corresponding email address: [email protected]
- mail.com is a primary domain, sub.mail.com is a second-level domain, and dev.sub.mail.com is a third-level domain. The second-level domain and third-level domain here are both subdomains of mail.com.
- A mailbox contains two parts: the email prefix and the domain name.
- For example, [email protected]
- dev is the email prefix.
- mail.com is the domain name.
- GetMX divides mailboxes into two types: main mailbox (also called administrator mailbox) and sub-mailbox.
- In most cases, the actual sending mailbox/actual receiving mailbox and the proxy sending mailbox/proxy receiving mailbox are the same.
- However, if email forwarding exists or third-party sending is used, inconsistencies may occur, or they may be distinguished in the receiving logs/sending logs.
- Main mailbox catch-all means collecting all emails from sub-mailboxes into the main mailbox. After main mailbox catch-all is enabled in the GetMX admin panel, even if a sub-mailbox has not been manually created in the GetMX admin panel, emails for that sub-mailbox can still be received in the main mailbox. If the sub-mailbox has been manually added, one copy of the email will be stored in both the main mailbox and the sub-mailbox. This eliminates the need to manually add sub-mailboxes one by one. You only need to enter any email prefix when using the mailbox, and emails for sub-mailboxes can be viewed in the main mailbox, enabling unlimited mailboxes.
- Sub-mailboxes created through catch-all cannot log in separately and can be viewed in main mailbox management. To log in separately, they must be manually added one by one.
- Sub-mailboxes are not created, but they are not virtual either. In
Domain Email--Email Manage--Recipient Sub-Mail, you can view all mailboxes that have received emails through catch-all.
- A shared server provides services for multiple domains, and network load is shared across multiple servers.
- Foundation and Growth are shared servers.
- A dedicated server has an independent IP address and is not shared with others. It is more stable and suitable for receiving large volumes of email.
- Scale is a dedicated server.
