What makes an tin nhắn address valid
What determines the validity of an email? Let’s dig deeper into the factors that define a valid tin nhắn address.
Factor #1: Thư điện tử address format
A valid tin nhắn address consists of two main components: the username and the domain name name.
Username (before @) identifies the tin nhắn address user with a unique name. Domain name (after @) represents the tin nhắn provider or organization hosting the tin nhắn tài khoản.
So, a valid tin nhắn address follows the format: [email protected]. However, there are specific requirements for acceptable usernames and domain name formats.
| Component | Syntax requirements | Valid tin nhắn format examples |
|---|---|---|
| Username | Allowed characters:
A period (.) is not permitted at the start or over. Consecutive periods or special characters (e.g., john…[email protected]) are not allowed. Special characters should be followed by one or more letters or numbers. |
[email protected] |
| Domain name | Consists of one or more parts separated by a dot.
The second part must be at least two characters, for example: .com, .org, .cc Allowed characters:
|
Factor #2: Thư điện tử address authentication
Not all tin nhắn addresses that are correctly formatted are automatically considered valid. The most important factor is that the tin nhắn address actually exists and is active on the mail server.
This is confirmed through authentication, a process that ensures the tin nhắn address is legitimate and verifies its existence on the mail server.
It involves checking the tin nhắn address by verifying its domain name through MX records and authenticating the tin nhắn tài khoản using SMTP server commands to tướng confirm its active status and ability to tướng receive emails.
