MailBee.Security Namespace

MailBee.Security namespace contains additional types specific to TLS/SSL functionality, S/MIME support, certificates and certificate stores, DomainKeys/DKIM anti-spam technology.

The option to connect to SSL/TSL enabled mail server is available at no additional cost. The same applies to DomainKeys/DKIM - it's considered as a basic feature. You can sign e-mails with DomainKeys/DKIM signatures and verify DomainKeys/DKIM signatures of existing e-mails (this is a popular antispam check, many mail services nowdays accept only DomainKeys-signed e-mails).

With the help of advanced features (Security.Powerup license required), the developer can:

  • Work with certificates and their Windows registry and file stores
  • Examine or validate server certificates and specify client certificates within TLS/SSL connections
  • Encrypt, decrypt, verify, and sign e-mail messages
  • Let the current thread programmatically impersonate another user (useful if the application needs to access resources, such as certificate stores, which belong to another user)
