Interesting read on self-hosting email, with perhaps some tidbits that'd be helpful for Cloudron in the future (i.e. monitoring)

An interesting read on self-hosting email, which I came across today (thanks "Awesome Self Hosted Weekly newsletter"), and thought others may find this interesting too: https://schumacher.sh/2021/05/10/running-a-private-mail-server-for-six-years-easy-peasy.html

@d19dotca I still have some concerns about self hosting email. I use my iCloud email mostly but for some things (spam) I self host one. I self host for clients as well. But for me it comes down to making sure I never lose access to email. If there’s one thing I trust apple/google/etc to do right is have uptime that is better than what I can come up with lol
Not to discourage it though it’s a great thing to do.

For critical things, that's what a backup MX is for.

I just set up Cloudron a few weeks ago, and I am slowly moving all my emails there (only personal, family and work stuff... so not many addresses, and not a lot of volume).
In my initial tests I only had issues getting delivered to Outlook and Yahoo and I haven't been able to figure out why. My IP is clean!
Now I am using Amazon SES and all seems to work smoothly

@atridad Uptime is only an aspect of it. Self hosted email system is resilient enough to allow for downtime up to a week.
I'm much more fearful of getting cut by an email provide: I have some protonmail email that was cut for an unknown reason, and let's not talk about Google horror stories where falling foul of any policy in any of their service will cut you off without appeal.
The key is to have control about the domain name, so you can reroute wherever you want at any point in time.

Was wondering what's the consideration with self-hosting of mail server if I have a domain vs purchasing mail hosting for companies.

@Stephanie_Sy the main difference is where the emails are stored when not in transit, which inherently gives you more control over what happens with your data. If you use a transactional email service you do end up losing some of that control, but it’s better than fully hosted email. Depends on what you value. Honestly imo email should never contain anything sensitive so I just try and avoid that when possible. Hope that answers your question.

This was the case up until a few years ago. Nowadays a large part is deliverability.
Every system on the internet can theoretically sent mails to any other system and this means that there are a lot of people actually using this to send spam. This has caused large providers to block out entire ip ranges and datacenters. So if you don't want to silently end up in the junk folders of gmail and office 365, your best bet is to send through them as well. Its not impossible to host your own mail, and there are still mail relays you could use to improve your chances, but it is definitely something to consider when self hosting mails.
