Provide a Certificate Vault to MailMan

See more POP3 Examples

Demonstrates the Chilkat MailMan.UseCertVault method, which provides an XML certificate vault to be searched for certificates and private keys when MailMan performs operations such as encryption, decryption, signing, or signature verification. This example builds a vault from a PFX, attaches it, and fetches a message that Chilkat can decrypt using the vault.

  //  Note: The path "qa_data/certs/certs.pfx" is a relative local filesystem path,

  //  Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
  //  connects and authenticates -- using the property settings above -- whenever a server
  //  operation requires it.  Calling the explicit connect/authenticate methods can still be
  //  helpful to determine whether a failure occurs while connecting or while authenticating.
