Module email_deliver 

Enums

TemplateReplacements 🔒

Constants

BASE_BACKOFF_SECS 🔒

BATCH_SIZE 🔒

JITTER_SECS 🔒

MAX_BACKOFF_SECS 🔒

RECIPIENT_ADDRESS_PURGE_INTERVAL 🔒

How often the sender asks the model to purge expired recipient addresses. The model then rolls its own 1 in 10 chance, so a sweep lands roughly every ten hours.

Statics

BASE_URL 🔒

The same variable the server reads into ApplicationConfiguration::base_url: a mailed link has to point at the environment that minted its token. Not FRONTEND_BASE_URL, which no overlay sets, so reading that sends dev and test links to production.

DB_URL 🔒

SMTP_FROM 🔒

SMTP_HOST 🔒

SMTP_MESSAGE_ID_DOMAIN 🔒

SMTP_PASS 🔒

SMTP_PLAINTEXT_PORT 🔒

When set, mail goes to SMTP_HOST on this port without TLS, for the local Mailpit in dev and test. Unset, the sender uses implicit TLS on port 465.

SMTP_USER 🔒

Functions

build_email_message 🔒

compute_next_retry_at 🔒

extract_smtp_error_details 🔒

has_io_error 🔒

infer_email_domain 🔒

is_transient_smtp_error 🔒

mail_sender

Sends one batch of due emails. warned_layouts is the updated_at of each layout last checked for problems, so each version is warned about once rather than every batch.

main

placeholder_bag_replacements 🔒

Turns a delivery’s placeholder bag into {{KEY}} substitutions. Nested objects and arrays are skipped: there is no sensible rendering for them in body text.

record_message_build_failure 🔒

record_non_retryable_failure 🔒

retry_window_expired 🔒

send_message

template_replacements 🔒

warn_about_layout_problems 🔒
