So, as the topic says, I’m going to set up a self hosted email service for myself, family and friends. I know that this one is a controversial topic around here, but trust me when I say I know what I’m getting into. I’ve had a small hosting business for years and I’ve had my share of issues with microsoft and others, I know how to set things up and keep them running and so on.
However, on the business side we used both commercial solution and a dirt-cheap service with just IMAPS/SMTPS and webmail with roundcube. Commercial one (Kerio Connect, neat piece of software, check it out if you need one) is something I don’t want to pay for anymore (even if their pricing is pretty decent, it’s still money out from my pocket).
I know for sure I can rely to bog-standard postfix+dovecot+spamassassin -combo, and it will work just fine for plain email. However, I’d really like to have calendar and contacts in the mix as well and as I’ve only worked with commercial solution for the last few years I’m not up to speed on what the newest toys can offer.
I’m not that strict on anything, but the thing needs to run on linux and it must have the most basic standards supported, like messages stored on maildir-format (simplifies migration to other platform if things change), support for sieve (or other commonly supported protocol) and contacts/calendar need to work with pretty much anything (android, ios, linux, windows, mac…) without extra software on client end (*DAV excluded, those are fine in my books). And obviously the thing needs to work with imaps, smtps, dkim and other necessities, but that should be implied anyways.
I know that things like zimbra, sogo and iredmail exist, but as mentioned, it’s been a while since I’ve played with things like that, so what are your recommendations for setup like this today?
I have Dovecot and Postfix running on Debian on a server in my closet. Works great for my needs
Check out Mail-in-a-Box
Great plan! We need more independently hosted email. I’ve been self hosting email for 20 years. Still running Postfix and Dovecot, but don’t have all the features you’d like though. I just wanted to chime in that I’ve moved from spamassassin to rspamd. And I’m happy about that. Given your experience in the hosting business I think you’ll like rspamd. One thing I have changed since a few months is have outgoing mail go through Amazon SES. I moved hosting from Linode to Hetzner and that turned out to be not so great for outbound delivery reputation. I didn’t want to migrate back to Linode so I bit the bullet and compromised with SES. That has been really working well, but I admit it is a bit of a step back from fully self hosting.
What’s the benefit of rspamd over SA? I’ve used SA since I first setup my mail stack years ago, and it’s been great. Cron jobs run nightly to train based on the contents of all the mailboxes’
.spamfolders, so it’s only gotten better with time.Not judging, just curious.
I’ve stuck with iredmail for years. Spin up a VM, grab the installer, and see how it performs for you.
I’ve been using mailcow for about a year and i am very satisfied, it checks all your boxes and is easy to configure and deploy over docker.
Just beat me to it…
The one thing that they don’t have yet last I updated, though they’ve been working on it for a while, is a prod ready LDAP/SSO connection. I had the dev branch working with Keycloak, but never got plain LDAP to function.
@ShellMonkey I use the Generic OIDC option, havent tried LDAP.
@IsoKiero I don’t know about “latest and greatest”, but your bog-standard solution seems about right; just add radicale into the mix, and you’ve got calendaring and contacts.
I’ve been playing with Stalwart-Email as a combined SMTP/IMAP server. Its open source and written in rust, still pretty early in development and I haven’t played with it enough to give any real opinion on the pluses or minuses compared to other software, but its worth taking a look at.
