Records the working chain and the two dead ends: port 25 gets the mail rspamd-rejected (dynamic home IP, no SPF alignment), and the missing PTR delays the 587 greeting enough that short-timeout probes look like a firewall block. Credentials live only in /etc/msmtprc (600). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Personal infrastructure notes
Two repositories back this setup:
doc (this one) and
scripts (the cron drivers
and their config files, deployed to /root/scripts on each host).
Start here:
- backup-strategy.md — what is backed up, by which tool, on what schedule, and how to restore.
- new-container.md — conventions for adding a service to ks4 (and getting it backed up automatically).

Conventions
- One markdown file per topic in the correct subdir, containing the full implementation notes, configuration, and troubleshooting notes.
- Containers are built from Debian/Ubuntu images and configured
exclusively through
incus exec/incus configso the doc is the single source of truth — rebuilding = re-running the script. - Adding a service to ks4: follow
new-container.md (no Docker in containers —
incus runs OCI images natively and
incus-composehandles stacks; data paths go intoscripts/restic-paths).
