This is the file generated by the test on NixOS: [test.pdf](https://github.com/Edinburgh-Genome-Foundry/Flametree/files/6565265/test.pdf) I guess "Hello" should be bold?

This might be supported by https://github.com/x0b/rcx.

I think the options are: - [Baïkal](http://sabre.io/baikal/) - [Radicale](http://radicale.org/) - [DAViCal](https://www.davical.org/) The obvious advantages of Radicale are: - Python instead of PHP - only one with a NixOS module Advantages...

You should try testing both, 18.03 and unstable, now that https://github.com/r-raymond/nixos-mailserver/issues/95 is resolved.

I am seeing ``` postfix/smtpd[10743]: NOQUEUE: milter-reject: CONNECT from example.com[X.X.X.X]: 451 4.7.1 Service unavailable - try again later; proto=SMTP ``` in my logs when I try to send a message....

No, I'm on unstable. Disabled the rmilter service for now.

That's a known issue with `nixos-unstable`: https://github.com/NixOS/nixpkgs/pull/38372

I commented out that line as well. Otherwise, no email gets delivered at all. I didn't try rebooting yet. But without rebooting, each mail sent to my server reproducably shows...

Newer version on unstable: ``` $ rspamd --version Rspamd daemon version 1.6.5 $ nix-info system: "x86_64-linux", multi-user?: yes, version: nix-env (Nix) 1.11.16, channels(rschuetz): "", channels(root): "nixos-18.03pre129076.831ef4756e3", nixpkgs: /nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs ```
