Past time to upgrade my email server I run my own setup with RedSleeve6-arm. I never successfully got the Centos7-arm working, but if interested you can see what I was doing at: http://medon.htt-consult.com/Centos7-mailserver.html I want something as turnkey as possible with RAID1 drives. So first level question is a small Almalinux platform with RAID. Will have to be Intel, not ARM, as the mail software tends to be Intel. I do want low power. Note my network server is a little, low-power QNAP TS-230 and I had to replace a drive with errors, so I am sold on RAID. Thus first a recommendation on a platform. 4TB drives would be overkill for my mail needs. Then email software. My current setup is file-based messages. So I have to think about that for any migration, but I SO want out of maintaining the software myself. Running an updater is all I want at this age (now 72). I found: https://geekflare.com/self-hosted-email-server/ And iRedMail looks interestingly easy for me. Modoboa looks a little harder. Mail will be the ONLY think on this system, so I should not need any docker setups. Anyone can point me where to get going? thanks
