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?
You may have already read this but I always think back to this blog post about self hosted email:
TLDR;
- Mail is not hard: people keep repeating that because they read it, not because they tried it
- Big Mailer Corps are quite happy with that myth, it keeps their userbase growing
- Big Mailer Corps control a large percentage of the e-mail address space which is good for none of us
- It’s ok that people have their e-mails hosted at Big Mailer Corps as long as there’s enough people outside too

My problem is what happens if my internet goes down when there’s an important email or something. I suppose I could run it on a VPS just in case, but that’s still not as reliable as an email service, nor is it necessarily cheaper.
So I pay for Tuta email. It’s €3/month, supports my custom domains, and generally works pretty well. My VPS costs €4.5/month, and I may get rid of it once my city finishes rolling out fiber because I only need it due to CGNAT. Neither is particularly expensive, but Tuta is really good value for what I get. If my family members want to join, costs will go up (€3/user), so I may consider switching if that happens.
You won’t be able to host email on a residential IP - all of them are on a permanent blacklist. I understand the money argument - and it’s a real argument - but host your own email is just so cool!
Good point. Does the same hold for popular VPS services? I’m behind CGNAT so I need a VPS regardless, but others may prefer to have it at a VPS if they want to mitigate extended service disruption (i.e. equipment dies while they’re on vacation).
SMTP retries. It’s resilient. If it fails a couple of connections it’ll even let the other side know it happened and when it’s going to retry. If it can’t get it to you in a couple of days it’ll let them know it was not able to deliver.
The rest stands true, hosted Mail is dirt cheap and is more reliable I’m trying to host it in a non-professional capacity.
