Email verifier created to validate emails through configured rules. Today, the project has the following validations.
- EmailAddressAttribute of System.ComponentModel.DataAnnotations to validate the sintax that indicates a string if has a valid format.
- Using ARSoft.Tools.Net.Dns to validate domain's MX of email. The idea here is use any cache's architecture to save whitedomains and invalid domains for multiple validations in a period of time.
- Using a regex to validate some rule based in a string.
Example:
var emailVerifier = new EmailVerifier();
// Adding default rules:
emailVerifier.AddRule(DefaultRules.SintaxRule);
emailVerifier.AddRule(DefaultRules.MxRule);
string emailToBeValidated = "[email protected]";
bool result = emailVerifier.IsValid(emailToBeValidated);
Console.WriteLine($"Result = { result }");You can create your custom rule inheriting IEmailRule class. You'll have to implement two methods. IsValid and IsValidAsync. Both, returns a boolean value that indicates if the informed address value is valid or not.
