address
A valid email address is an email address that is correctly formatted and exists on an email server. An email address is considered valid if it conforms to the standards set by the Internet Engineering Task Force (IETF) and the Internet Assigned Numbers Authority (IANA). In order to be considered valid, an email address must contain a username, an “@” symbol, and a domain name.
The username portion of the email address is the part before the “@” symbol and is usually the name of the person or organization associated with the email address. It can contain letters, numbers, and some special characters. It is important to note that the username portion of the email address is not case sensitive, meaning that “[email protected]” is the same as “[email protected]”.
The “@” symbol is a separator that separates the username portion of the email address from the domain name. It is important to note that the “@” symbol must be included in order for the email address to be considered valid.
The domain name portion of the email address is the part after the “@” symbol and is usually the name of the email service provider. It can contain letters, numbers, and some special characters. It is important to note that the domain name portion of the email address is case sensitive, meaning that “[email protected]” is not the same as “[email protected]”.
In order for an email address to be considered valid, it must conform to the standards set by the IETF and IANA. If an email address does not conform to these standards, it will not be considered valid and will not be able to receive emails.
