Self-Hosted SMTP Relay (Optional)

> For sovereign/self-hosted users who need to deliver mail to external providers without managed cloud.

Overview

Anoobot's default path is encrypted mesh delivery between anoobot users. Internet delivery is optional and uses your infrastructure, not anoobot.com:

Address typeInternet SMTP from anoobot.com?
you@yourcompany.com (custom domain)Your SPF/DKIM/DNS
user@anoobot.comNot supported as bulk sending domain

Recommended setup

  1. Verify custom domain in Anoobot (DNS TXT).
  2. Configure your MTA (Postfix, Exim, etc.) on your VPS with:
  • SPF: v=spf1 ip4:YOUR.IP.HERE -all
  • DKIM: signing key for yourcompany.com
  • DMARC: _dmarc.yourcompany.com
  1. Point Anoobot compose relay (future) or client SMTP settings to smtp.yourcompany.com:587 with STARTTLS.
  2. Monitor bounces via your MTA logs — Anoobot does not centralize self-hosted outbound reputation.

Rate limits (mesh)

Even on self-hosted, mesh sends are rate-limited (M1):

Abuse

Report mesh abuse via POST /api/v1/abuse/report. Admins can suspend accounts via POST /api/v1/admin/users/:id/suspend.
