Hey all,

I have given up hope of hosting my own mail server but was hoping for one that would serve as an archive -

  • downloads new emails via IMAP from my mail provider on a regular basis
  • allows my mail clients to connect via IMAP to view and search emails

Any suggestions for a docker solution for this?

Thanks

    I use dovecot for this. And thunderbird to actually move/archive the emails. I use caddy for many of my services, so I have pointed dovecot to caddys certificates (for “my.domain”), since it manages certificates through let’s encrypt. I had a plan to install postfix for sending internal emails from my self-hosted services, but it seemed like a bit of configuration and I got busy with other stuff

    I made an excerpt from my docker-compose.yml, but you probably have to figure out some things on your own

    
version: '3.4'

services:
  dovecot:
    image: dovecot/dovecot:2.3.20
    restart: unless-stopped
    volumes:
      - ./dovecot/:/etc/dovecot
      - /mnt/storage/dovecot/mail:/srv/mail
      - ./caddy/data/caddy/certificates/acme-v02.api.letsencrypt.org-directory/wildcard_.my.domain/wildcard_.my.domain.crt:/etc/ssl/cert.crt
      - ./caddy/data/caddy/certificates/acme-v02.api.letsencrypt.org-directory/wildcard_.my.domain/wildcard_.my.domain.key:/etc/ssl/key.key
    ports:
      - 993:993

    contents of ./dovecot folder:

    dovecot.conf
passwords

    contents of dovecot.conf (I think I searched online to find a good example, I don’t remember where from…)
