# Mail

## Setup

Self-hosted mail running on `nuremberg-a` (Hetzner, Germany) via [poste.io](https://poste.io) in Docker.

poste.io is an all-in-one mail server that bundles:

- Postfix (SMTP)
- Dovecot (IMAP)
- Rspamd (spam filtering)
- ClamAV (virus scanning)
- A web admin interface
- Webmail (Roundcube)

## Why a Cloud Server for Mail?

Running mail from a residential IP is a recipe for deliverability problems. Most major mail providers will either reject or silently drop mail from residential addresses. Hetzner gives a clean datacenter IP with a proper PTR record, which makes a significant difference.

`nuremberg-a` exists almost entirely to host the mail server. It's a low-resource machine for the purpose.

## Domain

Mail is set up for `pez.sh`. SPF, DKIM, and DMARC records are managed via Cloudflare DNS (via Terraform).
