Module sender 

Product-neutral mail sender implementations.

This module owns the repeated mechanics for in-memory test delivery and SMTP delivery through lettre. Product crates still decide how runtime settings are read, how delivery errors map to their API error model, which test email copy they send, and how deliveries are audited.

SmtpMailSender

Enums

MailDeliveryError

Error returned by shared mail senders.

Constants

DEFAULT_SMTP_SEND_TIMEOUT_SECS
