synapse: add mail config (currently broken) 
tl;dr: mail config works, but on trying to send mail synapse gets rejected by
postfix for using a too-old version of tls, as apparently tls in twisted (the
python library used for mail in synapse) is just hardcoded to v1, which our
postfix rejects.

```
postfix/smtpd[9737]: warning: TLS library problem: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol:ssl/statem/statem_srvr.c:1685:

```

This is a known issue [1], which should be fixed in the current version of twisted,
which will be in the next version of synapse.

hacc nixfiles

welcome to hacc nixfiles (haccfiles). this is the code describing our nix-based infrastructure.

structure

  • default.nix: Entrypoint to the config
  • common/: configuration common to all hosts
  • desktop/: desktop-relevant communication
  • modules/: home-grown modules for hacc-specific services
  • nix/: sources files, managed with niv
  • pkgs/: packages we built and don't want to upstream

working with the haccfiles

deploy:

nix build -f . deploy.$hostname && ./result switch

$hostname can be replaced with any hostname or group

committing to haccfiles

  • Golden Rule: DO NOT COMMIT TO MAIN
    • exceptions apply, if you are not sure where to commit, don't commit to main
  • split up commits, every commit is one atomic change
    • e.g. no big "did some changes" but instead "updated service x", "updated service y", "update service z"
  • follow the commit format: "$prefix$place: $change"
    • prefix: one of fixup, nothing
    • place: one of "modules/$module", "$hostname/service", "common/($place)", "pkgs/$pkgs" or "sources"
    • change: describe your change, don't go over the character limit where git starts hiding/wrapping
  • Exception: autogenerated messages (merge commits, reverts, etc)
