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.

// the mail object first, then the server settings and the envelope on it

IGPALMail mail = GPAL.Mail.ToGPALObject();

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

mail

.WithSMTPServerName("smtp.example.com")

.WithSMTPPortNum(587)

.WithUserName("sender@example.com")

.WithPassword("app-password");

mail.SaveSettings();

// The display name belongs to an address, so it follows the address it names

mail

.WithFromEmailAddress("sender@example.com")

.WithName("GPAL Automation")

.WithToEmailAddress("ops@example.com")

.WithName("Operations");

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

mail.SaveSettings((GPALFile)"config/mail.yaml");

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

mail.LoadSettings();

// Or load and redirect in one call

mail.LoadSettings((GPALFile)"config/mail.yaml");
