Host aliases let multiple domains point to the same BAconn instance and automatically show the right branding (logo, colors, from-address) — even for anonymous landing-page visitors.

  1. Configure DNS: point your reseller domain (e.g. partner.acme.com) via CNAME to baconn.quelltxt.de.
  2. Create the brand: Admin → Brands → New Brand → enter logo, colors, optionally your own SMTP details.
  3. Host aliases textarea: one hostname per line, max 50. Example: partner.acme.com + ats.acme.com.
  4. Save: cache is invalidated immediately — changes are live, no restart needed.

What happens server-side: on every request BAconn checks the Host header. If it matches an alias, the corresponding branding is applied — including for anonymous landing-page visitors.

Tier: white-label is an Enterprise feature (€699/mo). On Ultra (€449/mo), branding is only per logged-in user, not per host.
