My webserver also houses our mailserver. There's about six users on

I know (or think) I need to use doveadm-backup for this but rather
than reinvent the wheel (or use the wrong wheel altogether) I'm
wondering if anyone can recommend a good tutorial or wiki entry that
shows the best way to loop through the users and send their backups to
a remote server.
Assuming you're running *nix on your HTPC and can install your own
software on it a safe, secure and reliable way of doing it is:
- Since you're on dynamic IP at home, set up a VPN tunnel using the
mailserver as server and HTPC as client. OpenVPN is ubiquitous and
widely supported.
- rsync your mailboxes using the tunnel connection.
This way you can back up your entire server, not only the mailboxes.
You can add doveadm in the mix if you want, or use imapsync and so on
and so forth.
YMMV
