- Invitations: each user can invite two friends by email (sign-up works through the link even while registration is closed); admin-editable template, subject and sender. - Invitation sender defaults to the system-mail From address, which the SMTP account is allowed to send as (was postmaster@APP_DOMAIN, refused with 553 when the two differ). - Sign-in, sign-up and forgot-password fields show the fixed @domain after the typed name; the registration status reports it. - System mail gets a Date header; the invitation's plain-text part keeps its paragraphs and line breaks. - SMTP EHLO uses SMTP_HELO_NAME / APP_DOMAIN, not the container name. - DNS recommendations for the mail domains.
