Email

Releval uses SMTP to send emails for member invitations, email confirmations, and password resets.

Caution

Without a configured SMTP server, email-dependent features (member invitations, password resets, email confirmations) will not function. The initial Admin is still created from the RELEVAL_INITIAL_ADMIN_EMAIL / RELEVAL_INITIAL_ADMIN_PASSWORD bootstrap variables, which don't require email.

SMTP settings

Variable	Default	Description
Smtp__Host	(none)	SMTP server hostname
Smtp__Port	(none)	SMTP server port
Smtp__Username	(none)	SMTP authentication username
Smtp__Password	(none)	SMTP authentication password
Smtp__FromAddress	noreply@releval.co	Address emails are sent from. Set this to an address on a domain you control so invitations and password resets pass SPF/DKIM.

StartTls	Upgrade to TLS after connecting (port 587)
