Hi,I'm looking to set up a virtual server to send and receive email for a domain name and store the email for pick-up by users over POP3 and IMAP. Normally, I'd go for Debian and then configure Exim, Dovecot and others to provide a Let's Encrypt TLS certificate, SPF, DKIM, DMARC, SpamAssassin, etc. It's a long list of things to configure, test, and debug. But I was wondering if there's a turn-key off-the-shelf distro which makes this simpler. I'm not bothered about a GUI or web configuration interface. And it doesn't have to be Linux; I know FreeBSD is quite popular in this area, historically because of ZFS. A small-office/home-office distro might be he kind of thing. This isn't for a desktop user but an Internet server; a headless box accessed remotely. I'd like to hear of suggestions and especially any experience, whether good or bad.
I haven't done anything more than install it and test that it can send and receive mail so far, so can't provide a solid recommendation, but you may like to take a look at Docker Mailserver (assuming you're happy to install and work with Docker. Base distro isn't too important so long as it supports an easy Docker install, but I'm running it on Ubuntu 22.04 LTS quite happily. It bundles and provides configuration scripts for Postfix, Dovecot, Rspamd, Amavis, Spamassassin, ClamAV, OpenDKIM, OpenDMARC, Fail2ban, Fetchmail, Getmail6, Postscreen and Postgrey with support for LetsEncrypt and SASLauthd with LDAP support. That's largely pulled from the GitHub page. I'm working on replacing my Exim / Dovecot setup with it to see how it goes. It seems to be regularly kept up to date, with the last update 15 hours ago.
