  • I use syncthing to copy important files between pc, phone and proxmox server. Syncthing can be set up with version control so it keeps old versions of files.

    Only the proxmox server is properly backed up though. to a proxmox backup server running in a VM on said proxmox server. the encryptred backup files are copied to backblaze using rclone

    Not sure if this is what you are looking for, but it works for me.

    TLDR syncthing for copies between local machines, and proxmox backup server and backblaze for proper backups





  • 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…)
