Validate method returns CertificateValidationFlags value for the given certificate.

When checking S/MIME signatures of e-mail messages, you can use Verify(MailMessage, MessageVerificationFlags, CertificateStore) method which can perform complex verification of the message signature including validating its certificate.

When making SSL connections to mail servers, you can set AutoValidation property to tell MailBee to automatically validate the server certificate accordingly the specified criteria and throw MailBeeCertificateValidationException if the validation process fails for any of the criteria.
