MailBee.NET Security components enable .NET applications to sign, verify, encrypt, decrypt e-mails, work with DomainKeys/DKIM, S/MIME, SSL/TLS, public and private certificates (including PFX), use MailBee.NET SMTP/POP3/IMAP components to connect to secure mail servers (like Gmail and MS Exchange) in both dedicated and STARTTLS modes, use impersonation.

DomainKeys/DKIM and SSL/TLS support is available at no additional cost, only the corresponding MailBee.NET SMTP/POP3/IMAP license is required. Using ceritificates and S/MIME does require separate MailBee.NET Security license.

- supports connections to dedicated SSL ports and to regular ports (STARTTLS);
- client and server certificates;
- validation of the server certificate;
- certificate and certificate store management (reading from or saving into a file, registry, memory, etc);
- enumerating and finding certificates in certificate stores;
- supports private certificates and PFX format;
- digital signatures;
- S/MIME features: sign, verify, encrypt, decrypt messages;
- security algorithms, CryptoServiceProviders, etc;
- DomainKeys anti-spam technology (creating and verifying DomainKeys and DKIM signatures);
