Space-agent and mailbox emails set From to {slug}-agent@rspace.online but
the envelope MAIL FROM was noreply@rmail.online. Rspamd DKIM-signs with
the envelope domain (rmail.online), which fails DMARC alignment against
the rspace.online From header — Gmail was quarantining invites.
Set envelope.from to match the From header so rspamd signs with
rspace.online's DKIM key and SPF/DKIM align. Verified via test send:
DKIM_SIGNED{rspace.online:s=dkim}, FROM_EQ_ENVFROM, no DMARC:Quarantine.
Covers: space invite emails (identity + existing-user paths), agent
notifications, rinbox MI agent blasts, mailbox approval sends.
SMTP auth on port 587 was broken across all modules due to stale
credentials. Since rspace is on the mailcow Docker network, all 6
SMTP transports now use unauthenticated relay on port 25 when the
host is the internal postfix container. Fixes emails for: payment
receipts, space invitations, inbox approvals, agent notifications,
scheduled emails, and publication sharing.

Each space gets {space}-agent@rspace.online as a real Mailcow mailbox
(auto-provisioned with generated password). Inbound emails are IMAP-polled
and processed by MI (Gemini Flash) for auto-reply. All outbound emails
(approvals, notifications) set reply-to to the agent address so replies
route back through MI.
