E-mail and notifications

The variables behind outgoing mail (notifications, password resets) and browser push. Mail is normally set up in the panel, as described in E-mail and notifications; the variables are its fallback.

E-mail (SMTP)

The variables are read at startup and used while the Email / SMTP card of Admin → Server Config has no host. Once a host is saved there, the card provides every field and applies without a restart.

EVEY_SMTP_HOST	empty	The mail server. Empty: no mail is sent.	Server Config → Email / SMTP → SMTP Host, live
EVEY_SMTP_PORT	587	Its port.	same card → Port, live
EVEY_SMTP_USERNAME	empty	The account to sign in with.	same card → Username, live
EVEY_SMTP_PASSWORD	empty	Its password.	same card, live
EVEY_SMTP_FROM	empty	The sender address, for example noreply@example.com.	same card, live

Browser push

Variable	Default	What it does	Panel
VAPID_PUBLIC_KEY, VAPID_PRIVATE_KEY	generated	The key pair that signs push notifications. When absent, the server generates one on the first start and stores it in the database; set them only to keep a pair you already use, and always both: one alone disables push with a warning.	none
