Entry Points, Flags & Environment

Reference: Entry Points, Flags & Environment

This page documents the environment variables used by the mailer package to configure transactional email delivery. These variables are read by the application to determine whether to send emails via an SMTP relay or fall back to logging them to the server console.

Environment Variables

TELA_SMTP_FROM

• Location: backend/internal/mailer/smtp.go:41 — os.Getenv

TELA_SMTP_HOST

• Location: backend/internal/mailer/smtp.go:27 — os.Getenv
