Then, import the required namespaces at the top of your code file:ĮmailAddressValidator valid = new EmailAddressValidator( "MN110-0123456789ABCDEF-0123") ĭim valid As New EmailAddressValidator( "MN110-0123456789ABCDEF-0123") NET 4.5+ case), see similar topic in MailBee.NET SMTP guide. To learn how to add a reference to (or MailBee.NET.45.dll in. To start with Address Validator, you need to add a reference to, import namespaces and unlock the component. If the server accepts the recipient and says "Yes, I'm ready to receive message data", the component just resets the connection and disconnects, reporting that the address is correct. This mimics normal send attempt, just without sending actual message data.

SendAttempt - test connection, sending EHLO/HELO and MAIL FROM commands, and submitting the given e-mail address string in RCPT TO command.

SmtpConnection - test connection to the SMTP MX host.

DnsQuery - DNS MX lookup for domain part of the the e-mail address string, to find out the SMTP MX host responsible for e-mail delivery to the domain.

RegexCheck - syntax check of the e-mail address string.

The following validation levels can be set with EmailAddressValidator.ValidationLevel property (defined by AddressValidationLevel enum): NET Core and UWP editions, only single addresses can be checked at a time. As for memory usage, it stays stable and won't increase even if you run the check for many hours or even days validating millions of addresses. Another important performance optimization, DNS caching, is also supported, and enabled by default. You can enable it with setting EmailAddressValidator.MaxThreadCount property. The component can check both single addresses and bulks of hundreds of thousands.Īddress Validator supports multi-threading (up to 60 threads) which greatly improves performance and enables up to 100.000 address checks per hour in the most accurate validation mode, SendAttempt.

DNS servers, caching, local endpoints, SMTP settingsĮmailAddressValidator component lets you verify e-mail addresses for correct syntax and, optionally, for existence.

With this effective four-step verification, Atomic Mail Verifier allows you to weed out the maximum number of nonexistent addresses, as well as prevent the removal of those that are truly valid. Mostly the rule for such status is that this server accepts all emails sent to it even if the email on the server is non existent and overall we recommend to avoid such emails in your campaigns unless absolutely necessary, because there is not way to validate those For instance, we validated in the log you can see the app generated a random address with the same domain, in this case (so it should not exist), but the server replied that it exists, thus we can not state that exists for sure. If a server responds that a generated email is valid, a defined email you aimed to validate will be marked as "email domain has a catch all function enabled".

Catch all status check: regrading a catch-all status, on the fourth step of verification the software generates a random email with the same domain.This step is only possible if you have port 25 open. Email address check: the program searches for a domain's SMTP server, and checks for user existence.If a domain does not exist, the electronic address with that domain also does not exist Domain check: all domains are checked for existence.Syntax check: email addresses are checked for correspondence to the RFC registration.
