GPAL Fluent: High-level fluent C# API

//SaveSettings() and LoadSettings() persist and restore all server connection settings. With no argument both use ./GPALMail.yaml. Passing a GPALFile sets that path as the session default -- subsequent no-arg calls use it for the rest of the run.

// Save server settings to the default path (./GPALMail.yaml)

GPAL.Mail

.WithSMTPServerName("smtp.example.com")

.WithSMTPPortNum(587)

.WithUserName("sender@example.com")

.WithPassword("app-password")

.WithFromName("GPAL Automation")

.SaveSettings();

// Redirect to a custom path -- becomes the session default

GPAL.Mail.SaveSettings(GPAL.File.WithFileName("config/mail.yaml"));

// Load from the session-default path (no arg needed after redirect)

GPAL.Mail.LoadSettings();

// Or load and redirect in one call

GPAL.Mail.LoadSettings(GPAL.File.WithFileName("config/mail.yaml"));
