Module: ThecoreBackendCommons::SmtpConfig

Defined in:
lib/thecore_backend_commons/smtp_config.rb

Overview

Reads SMTP settings from ThecoreSettings (ns: :smtp) and builds the delivery_options hash for ActionMailer / Net::SMTP.

Port 465 → SMTPS (implicit TLS from the first byte): tls: true. Port 587 → STARTTLS (plain connection upgraded after banner): enable_starttls_auto. The two modes are mutually exclusive; mixing them causes a ReadTimeout.
