Slaps board of Pi this bad boy can fit so much fucking dust in it.

i run homeassistant, pihole, 2 projects of mine using NodeJS, nextcloud, a very simple static website and Nginx for some DNS customization like pointing nc.home to a specific port. My pi is a 4GB one and for now the used RAM is not even 1 GB. I run debian with no graphical interface

How long is a piece of string?

Yes.

Xmpp, irc, email and websites are all pretty small in terms of resource usage. Where you’ll have problems are with heavy compute workloads like 3d rendering, AI, 3d gaming (sorry, no crysis), and crypto mining. They all can be done on a rpi but not done well.

I have mine hooked up to my PS2 with a dead disc drive to serve ISOs over the Ethernet port. It hosts a samba share so I can just dump ISOs from any device on LAN.

Sure it can, but it depends on what software you run and how much load you put on those services.

That’s a great thread. That’s why you don’t want to host your own email. Well, if you’re planning to use it as a daily driver for an extended period of time. There’s guys who are out there with basically just managing that process as their full time job. (Not really, but almost — when does a hobbyist have that kind of free time?). You know there’s things like shinobi and private Servers that would likely see your server responding to port 25 in a few hours and it’s going to be game on for how good your security practices have been. I don’t want to expose my internal network to that as I’ll likely have file servers not too far off with security practices that are intended to be behind a firewall. But hey, if the guy wants to do it, he can.

Also of note which may be mentioned elsewhere-without business class service at your location, most ISP’s block mail, http and other ports at their side, so you’re dead in the water anyway.

NEVER transcode. Do it as a background task offline. Even GPUs and desktop servers are best offline.

If you **really** want to host your own email then grab a cheap/free domain name from somewhere and use that instead of your main domain/address for your testing ans setup

Do all your learning on that email account and domain name that you can throw away.
Once your comfortable then you can think about forgetting about moving your main address as it’s not worth the hassle! :-D

If you want email, just setup Zoho free

Don’t need to transcode though. Most devices can directstream completely fine

Pi 5 is out very soon.

Ok here it goes…

Many on this sub will start an echo chamber. They will tell you how you should never host e-mail. Never! And how this plan, and that host, is so much cheaper. It’s not worth the headache. Oh the headaches. Bla bla bla. They think because they don’t want to do it, no one else should.

If you want to learn how to host your own e-mail. Do it! Just don’t plan on using that e-mail for anything mission critical. At least not in the beginning.

Oh and your Pi4 is more than enough to do what you are trying to.

Is capable of seven

I had Docker Container mini server running on RPi4 + HDD enclosure with 4x2TB drives for almost 2 years. If i remember correctly - i had 18 or 20 containers. Usual stuff like PiHole, Plex, Transmission, FileBrowser and other stuff.

Not once i had any problems with this setup. One of the reasons i switched from RPi4 to Intel NUC + Proxmox - some of the stuff i self-host for work only available for x86 platforms.
