The site you're reading is the launch
The quest hub went public - this page, the receipts, the real token costs, all of it. Two days after the mail server was born, the story of building it became the launch surface itself.
Public build
Agent-Native Email
Email stresses me out. It's critically important, but it's noisy and annoying, and I always feel like I'm missing something or someone important. Yes, I've tried automated tagging, Superhuman, Cora, and a half dozen other tactics to tame the monster - all to no avail.
This thriving quest is to master my email inbox + outbox by building a net new, agent-native email infra stack. I want to own my email end to end: a self-hosted server, an agent village to manage all the pieces, and real token cost accounting along the journey.
Current problem
Email is a useful and necessary tool - connection, collaboration, coordination, and more - but the stream of emails can be overwhelming and counterproductive.
Thesis
Agents can cost effectively and accurately manage every aspect of a secure, private email architecture from the ground up.
Current progress
It's working! Self-hosted mail server receiving emails, an EA agent triaging the live inbox, and solid documentation along the way.

The build blueprints
I find better outcomes when I spend more time than you'd expect on drafting and editing the plans. I like to organize my documentation from a first principles approach with explicit decision and change logs - that way I always know where I started and how I got to where I am today.
Most importantly, it helps me organize my thoughts for how to support others who also seek this thriving quest.
Design intents
- Agent-native foundation - every component managed over SSH, APIs, and CLIs; no browser puppeteering
- Eval-first planning - success criteria written first, tested continuously
- Tech independence - my domain, my server, my data; any vendor swappable in an hour
- Anti-slop publishing - a human gates everything public
- Radical receipts - the journey published as it happens, token costs included
Success criteria
- Done: Mail from the big providers received, and 10/10 test sends landing in their inboxes, not spam
Status (2026-07-10)
The server is alive. My thrivinghenry.com mailbox receives on a self-hosted OpenBSD box - MX cutover complete, first real mail delivered in under a second. Outbound sends through a self-managed relay: the host refused to open direct port 25, so I routed around it with the break-glass path I'd designed in from day one. The EA agent triages the live inbox daily. The village of agents and daily brief are the next big pushes.
What's working
- Owned hardware - receiving + sending works on the self-hosted server
- Live restore - the full server was rebuilt from backup in 5 minutes 28 seconds
- Model v. model - I used Fable and Sonnet to review each other's work. They did a good job catching each other's oopsies.
- Security hardening - Since agents read every email, I protect against prompt injections
- Newsletter ported - moved newsletter to Resend with forever home service account
What's not (yet)
- The daily brief's delivery surface is a placeholder
- The village of agents is not fully designed and untested
- Recursive loops are not fully designed and deployed
Next
Finish the newsletter relaunch, make the daily brief genuinely useful, then grow the agent village seat by seat.
Key milestones
Trailhead mappedCompleted milestone
Design spec approved before any building: mail server, newsletter relaunch, this hub, and a five-seat agent team - success criteria declared first.
Received inbound email at honey@thrivinghenry.comCompleted milestone
Mailbox receiving on owned OpenBSD hardware. MX cutover complete; first real delivery in under a second.
Changelog entry →First agent hiredCompleted milestone
The EA triages the live inbox at 100% on its golden-set eval - and flagged a prompt-injection attempt instead of obeying it.
Restore drill: 5m28sCompleted milestone
The full server was rebuilt from backup during a live drill - target was four hours.
Outbound deliverability gatesCompleted milestone
10/10 on mail-tester through a self-managed relay (the host blocked direct port 25, so I routed around it) - SPF, DKIM, and DMARC all green.
Newsletter on owned railsUpcomingUpcoming milestone
Thriving with AI relaunches with replies landing in the new mailbox - the agent team's first real traffic.
Site + quest hub publicCompleted milestone
This page ships with the site relaunch. If you're reading it, this one's done.
Five-seat agent orgUpcomingUpcoming milestone
Sys Admin, EA, Editor, Publicist, Chief of Staff - with a nightly self-improvement loop.
Gmail becomes a burnerUpcomingUpcoming milestone
The win condition: nothing important lands at the old address anymore.
Quest log
Outbound went live the day the host said no
The hosting provider refused to open direct outbound - so the relay path designed on day one took over. Messages queued for 23 hours flushed in seconds, and the whole stack scored 10/10 on mail-tester. The foundation workstream is complete.
See the PR →Four pages designed and built in a day
The launch surface went from route inventory to four reviewed page redesigns in one day - drafted as design cards, edited in a shared design pane, shipped as pull requests. 30 routes went dark; 13 pages remain, crawl-audited clean.
See the PR →The server is alive
My thrivinghenry.com mailbox now receives on hardware I control: MX cutover done, first real message delivered in under a second, and an EA agent triaging at 100% on its golden-set eval.
The trailhead is mapped
Design spec approved before any building: a self-hosted OpenBSD mail server, a newsletter relaunch on owned rails, this quest hub, and a five-seat virtual agent team - with success criteria declared up front.
What this costs
Real token spend, per workflow, from the agent run logs. I have yet to see anyone publish this level of detail, so I have no benchmarks or comparables. I don't have a feel for what I believe is the right cost for a daily run, and tracking closely is the fastest way to get there.
Note: I am not counting my $100 Anthropic and $100 OpenAI subscriptions. They are amortized across consulting gigs.
