I self host on my domain and on my renter hardware (not from home I mean) since probably 20 years. Changed ip a few times due to provider replacement and rented hardware upgrade, but I never had issues whatsoever, at least serious.

Whoever complains about self host mail didn’t setup dkim/dmarc/SPF/proper DNS entries or is using some residential address pool, because really nobody filters you that much. I also self host mail for newer domains and again never had issues.

I had issues with an idiot sending spam from his account (relatives, the worst) but I banned him and unblocked my domain once, never had the issue twice.

I recently updated my wiki with all my instructions here https://wiki.gardiol.org/doku.php?id=email%3Astart

I wrote it for me, to remember what I did, but thought it might be useful for others. All bare metal, no containers, you learn what you do.

Is pop3 still a thing?

Anyway, more clear now, can make sense (not to me, I self host my mail on my VPS)

Sorry, not clear to me what this accomplishes. Yes you buy a domain and use it for your email, then if and when you switch, you also migrate imap-to-imap all your email… It’s a pretty easy thing to do and there are tools just for this purpose.

Is this a script to do the same?

3, 2, 1… Test the backup!

… Is that the rule, right?

I have been using the link to share… Its not a weird thing, just a filesystem link between radicale users…

But if now it’s easier to manage, good to know… Let us know!

Update : my ISP does not provide GUA… So, whatever. Stick to IPv4 for the time being, no need to get complicated with IPv6 nat when I already have IPv4 nat working fine.

I actually have two ISP and one does support ip 6 with a GUA and that’s where I got confused… Unfortunately, it’s the one providing 20mb/sec FTTC that I use only for backup. The main one, the one providing 300mb/sec over FVA does not.

Mostly because my files stay on my hardware, on my network. In case of internet down/broken/filtered I can still access all my data. That is one of the points of self hosting. Not the only one, granted, and maybe not even the most critical, but having the opportunity, better to host on your turf.

Go ahead the self host on a cloud somewhere, nothing bad about that! Have fun, enjoy, learn and be digitally independent is the core of self hosting.

Ok, i misunderstood!

Why use an external cloud? While its technically still kind of self its not self hosted anymore IMHO. You would still be running your services, but on somebody else, rented, hardware. While I do the same for a few services (like email), i wouldn’t suggest it for general services that you want to reside on your turf (like immich, music, 'arrs, passwords, whatever)

How do I find out if the ISP is handling me a single address or a /64 or whatever?

Mm no, not using dyndns. I am missing IPv6 support on the LAN side… But I have it on the wan side

Nope, no vpn

Ok cool to know, never done raid1 since the time I moved to btrfs…

That seems overkill, in fact my 20y old only address still works pretty fine, and with rspamd setup, with basic settings, the annoying few emails have been intercepted now.

But indeed an extreme but effective approach, yours.

Thanks…wa easier than I thought to set it up, have updated my wiki but still a work in progress.

Do you have documentation or references on how to setup rspamd?

What? I have opnSense how would I filter spam with it?

Zfs for some reasons is always loved by the self hosting experts.

Personally I don’t like it because it’s over complicated and not officially part of the Linux kernel.

20y of self hosting for me means Linux software raid (raid1 then moved to raid5) and mostly ext4, recently (=last 2 years) upgraded to btrfs on my data raid. Btrfs at least is integrated in the Linux kernel and while has some drawbacks (don’t do raid with btrfs, put btrfs on MD raid instead) its been super rock solid.

I would have kept ext4, but thought why not try btrfs, and it’s been so smooth that I had no reasons to go back.

We don’t need fake ai written posts against AI.

And frankly the only believable thing is the AI hallucinating.

Even the point that auth was missing is not believable.

The 80% is useless, batteries are not built to be charged continuously. I suggest you use a smart plug that you turn on and off periodically
