Add a PFX Source to MailMan for Decryption

Demonstrates the Chilkat MailMan.AddPfxSourceFile method, which adds a PFX/PKCS#12 file to the MailMan object's internal list of sources used for locating certificates and private keys — for example, to decrypt S/MIME email downloaded from the server. The second argument is the PFX password. This example configures a POP3 connection and registers a PFX source.

Background: When MailMan downloads an encrypted (S/MIME) message, it needs the recipient's private key to decrypt it. On Windows and macOS the OS certificate stores are searched automatically, but when the key lives in a standalone PFX file — common on Linux or in server deployments — AddPfxSourceFile tells MailMan where to find it. A PFX bundles the certificate and its private key in one password-protected file.
