Unique selling point
Assistants that stay in the house.
Every user can create sub-accounts for AI agents — with their own address, their own mailbox and clear boundaries. What they process never leaves your server.
What we mean by that
An agent is not a chatbot that answers your mail. It is an account of its own, with rules: an address like quotes@your-company.com, a mailbox, and a definition of what it may do on its own and what not.
We spell this out because “AI” can mean many things these days. What AnnexGroup provides is the infrastructure for it — accounts, boundaries, a review loop, an audit log. Which language model you connect, and for what, is your decision.
Four autonomy levels
| Level | What the agent may do | Where it makes sense |
|---|---|---|
| 0 — Observe | Read only. No sending, no changes. | Onboarding; understanding what comes in at all. |
| 1 — Suggest | Write drafts. Every send requires approval. | The default at the beginning. |
| 2 — Act within limits | Send autonomously within the defined boundaries; everything else goes to review. | Recurring matters with a clear pattern. |
| 3 — Autonomous | Acts within the set frame without a prior draft. | Only after you have watched what the agent does for weeks. |
The review loop
The actual core. Anything an agent is meant to send or receive can go through a review list first. There you see the full text and decide: approve or reject.
An approval then actually delivers the message — with everything that belongs to normal delivery: filter rules, categories, attachments, search index. A rejection means it reaches nobody.
Further boundaries
Incubation period
For a fixed number of days, the agent stays below its level. After that, the configured autonomy applies.
Time windows
Weekdays and hours during which the agent may be active. Outside of them, everything sits in the review list.
Manipulation protection
Incoming messages are checked for patterns that try to smuggle new instructions into an assistant. Anything suspicious goes to review.
Audit log
Every decision is recorded — what was delivered, what was held back, and what was rejected for which reason.
Why nobody else offers this
The research for our competitive analysis found, among the established self-hosted servers — Kerio Connect, MDaemon, SmarterMail, Axigen, IceWarp, Carbonio — none that ships AI agents. Microsoft and Google have them, as an add-on at $21–30 per user and month, processed in their data centres.
Whoever wants both — assistants and data sovereignty — had no choice until now. That is the gap AnnexGroup aims at.
