From 2c24c3f2f6acd1a08c0345990f14531e4df4b337 Mon Sep 17 00:00:00 2001 From: Benjamin Date: Mon, 6 Oct 2025 14:04:42 +0200 Subject: [PATCH] feat: add SMTP email service with signature reminders Add configurable SMTP service for sending signature reminder emails. Features: - Configurable via ACKIFY_MAIL_* environment variables - Multilingual templates (en/fr) with HTML + text versions - Template rendering with automatic variable injection - Graceful degradation when SMTP not configured - TLS/STARTTLS support with configurable timeout - MailHog integration for local testing --- docker-compose.yml => compose.yml | 0 go.mod | 5 +- go.sum | 6 +
