imapsync

Following that, I installed fail2ban and iptables, and configured the firewall properly. Setup DKIM with this guide, then I rented a VPS for $4 a month as a backup MX, and hooked up two 240GB SSDs in RAID 1 to the Pi for storing all the mail. I used imapsync to transfer about 10 accounts out of Google, then made half a dozen new accounts on a different domain, too. I've not had any problems with deliverability on either domain after speaking to my ISP about configuring rDNS, and the only maintenance I've done is the occasional apt update && apt upgrade -y.
