Self-Hosted Main

E-mail

A password manager because if anything goes wrong, you'll be completely screwed.

What you SHOULD absolutely self host though is a password manager, so you can be in control of your most sensitive data.

Regarding email, I think everyone should absolutely self host it, but it's less and less viable in this google/Microsoft duopoly world. But ideally everyone would self host it. The reason why people advise against it really comes down to lack of real competition, and the two tech giants dictating how we violate every RFC possible.

Okay I understand that email hosting is bad for SENDING email , but what about only RECEIVING email , isn’t it a good idea to keep my stuff private ? I rarely send personal emails, and like to avoid my data being used for marketing purposes Is that bad to have smtp imap open on dynamic ip address ? Just asking your opinion

Passwords:
-> You want to have immediat access to them, even if your house burns down

Notes:
-> You want to be able to read the documentation how to fix your selfhosted service, even when your selfhosted services are down

Public Reverse proxy:
-> A reverse proxy is only as safe as the applications behind. And NO, most selfhosted-applications are not hardened or had security audits
(reverse proxy with a forward authentication proxy is something different)

In my opinion, cloud storage for (zero knowledge) backup. Your backup strategy should include a diversity of physical locations. I had a house fire a few years ago. Luckily, my data drives survived, but if they hadn't, my cloud backup would've been invaluable.

Don't host your own email server.

Just trust me.

I'd say backups. At least it shouldn't be only local. I follow the rule of threes: two local copies and one off site with backblaze. Yeah, it ties up a not insignificant amount of disk space I could use for other things, but dammit, I'm not loosing my wedding photos, important system configurations, etc.

Primary backups

People saying email, look into using external SMTP servers as relays. Your domain most likely comes with at least one email account with SMTP access. You can use that as a relay to send personal/business emails from your server using the provider's reputable IP addresses.

Internet-accessible authoritative DNS nameserver(s) (unless you have a completely static public IP).

Personally I don't think it's worth hosting recursive dns resolvers. Most of the options with ad blocking are single points of failure and when it breaks the household acceptance factor is just too low.

The login page to your NAS.

Email

I think there's a hangup on the term "self-host" where some people are assuming it's going to be exposed to the Internet.

I self-host a ton of stuff that is only available inside my home network or through my VPN, which is not publicly discoverable. I would never open a TCP port to the world from my home network. That's how you end up on shodan.

So yeah, if it has to accept inbound connections from arbitrary other systems on the dirty internet (email, mastodon, etc), it's not happening on my network, and probably not at all because it's a pain in the ass to stay patched.

Some generic purpose LLM probably.

Aside from other stuff mentioned here about email. I always assumed I'd become a target for spam that I'd have a harder time filtering out to the point it stops being worth it to have a custom email address.

That and I can almost guarantee I would end up screwing up the backup of my inbox and losing everything rending the whole endeavour pointless.

I don't self host anything where it would impact me unduly if it went down while I was on holiday to the point where I'd have to break state and go fix stuff.

I don't want to have to leave my beer or beach and head off to fix things like an email server, restore a password manager db etc. so anything like that which is critical to the point where an outage would prob have me do so means I pay someone else.

Tor exit node. Too much legal stuff.

Mail server or anything using RDP.

Email

Push notifications.

It is fine hosting a service that gets requests then talks to FCM or the iOS version. But a service that one's phone stays connected to 24/7 is really hard, and not kill one's battery.

email service

A CDN

Email. I always recommend AWS SES. Use it at as an SMTP relay and any internal services gets restricted access through IAM.

If self hosting from home.. email servers

At home, your IP is likely blacklisted and/or your provider has blocked the necessary ports. Not to mention the layers of potential headaches dealing with potential spam block dbs, especially if you don't own your IP.

You can of course do custom setups allowing you to skirt these restrictions, but can sometimes be a bit complicated and typically involve non-traditional customizations.

E-Mail.

And maybe unpopular opinion:

1. Any service that you use with port-forwarding, besides WireGuard.
   I would never access any self-hosted application without VPN.

2. Password manager. I want to minimize complexity with my most important data (that's why I'm using KeePass instead of Self-Hosted Bitwarden).

Plex. Despite everything be supposedly self hosted, they are spying on what you're watching and sharing that info with 3rd parties, your friends and your family.

Use Kodi instead or if you're old school like me, an old fashioned smb share running on a pi.

Child porn, obviously

Clearly opening RDP port on internet. NEVER.

Mail is a waste of time, and it's take the risk to don't receive important mail in time.

Password manager. While some may cache on your client devices, by and large if your server goes down, no passwords.
