Commit d8681e4

Repository	bojemoi
Branch	main
Author	Betty
Hash	d8681e42dc2234a4cbe9cff32d5fe1b37cb5388f

Description

Service mail-watchdog (Python, port 9355) qui envoie un email de test toutes les 10 min via postfix:25 → protonmail-bridge pour valider la chaîne complète. Expose 4 métriques Prometheus :

• mail_watchdog_last_success_timestamp
• mail_watchdog_send_total / send_failures_total
• mail_watchdog_send_duration_seconds

Alertes ajoutées : MailWatchdogDown (scrape KO 5m) + MailSendFailed (aucun succès depuis 30min). Alloy config bumped v5 → v6.

Fix: MAIL_FROM=watchdog@bojemoi.lab (postfix reject_unauth_destination n'autorise que les senders du domaine bojemoi.lab).
