Oh god, yeah. I personally would not try to self host e-mail or any service that you need other people to be able to reliably connect to without a static IP. As to losing power… In theory mail servers are supposed to queue mail and resend later, and you can also set up a backup MX that will queue mail for you (senders will automatically switch to the backup mail server if they cannot connect to your primary one). There are even free services for backup MX junkemailfilter.com/…/free_mx_backup_service.html (though they use this to train spam filters, so if you have privacy concerns you may want to avoid it). In the past I have had some prolonged downtime on my mail server and I have noticed that some senders will give up entirely and never send to that address anymore (which I think is poor form on their part, especially since somebody could register that email account later). I’ve since setup my own backup MX to avoid these issues, and it’s worked great when my primary has had network issues (needed a spare box for backup nameserver and stuff anyway, haha).
You absolutely can use an external mail service as a catchall with your own domain. For instance protonmail has support for this:
You’d have to look into the pricing and read the fine print, though. A lot of mail providers charge per inbox and I’m not sure if they’d charge extra for catchall services or not.

Appreciate your input :)
Proton mail allows catchall with a paid plan, the least expensive of which is about $4/mo. They have an excellent reputation. But then there’s fastmail which is like, all of this batteries included, including bitwarden integration for auto creating the email aliases. And it’s cheaper. Well, guess I’ve got some research to do. Thanks for the guidance, you’re really helpful :)

Glad it was helpful! I was worried I’d be a little off-topic talking about self-hosting e-mail instead of this Anon Addy thing. Hope you find a solution that works for you soon :).
And yeah… Unfortunately if you you’re behind CGNAT and don’t have a static IP I think doing this for free on your existing internet connection might be challenging. One thing that people in a similar position might be interested in is Hurricane Electric’s free Tunnelbroker service, but I think you might still be out of luck behind CGNAT.
You’ll be able to get public IPv6 addresses for free and can allocate them to your home network. You can set it up to dynamically update the IPv4 address on your end… But I think if you’re behind CGNAT you can’t do that, unfortunately. Another problem with this approach for something like a mail server is that not everything speaks IPv6… If a sender only supports IPv4 they won’t be able to send mail to you.
I think behind CGNAT pretty much your only option is to pay somebody for a real IP somewhere. Either a VPS somewhere where you set up wireguard (there are cheap options for this, and then you can run other things on the machine), or a VPN with a dedicated IP.

I was considering a VPS! That said, if I’m say, accessing my jellyfin library externally through a VPS, wouldn’t that just end up costing ludicrous amounts of money?_
Chobbes@lemmy.world 1 year ago
Depends on your usage, but probably not? If you can transcode on your jellyfin server you’ll be able to serve lower quality versions remotely if you want to save bandwidth… But most VPS’s provide around a terabyte of bandwidth per month by default. If you use more it will cost more. I think it’s usually fairly cheap to get more, but if you’re the only one accessing it you’re probably not going to use that much. Like if you rip a blu-ray you might end up streaming a 50gb or so file for a movie, but that’s only a twentieth of the bandwidth allotted to you (roughly)… Plus if you reencode it to something smaller before putting it on your jellyfin server, or if your jellyfin server can transcode fast enough you can send a smaller video stream to your mobile devices or whatever.
I don’t either, that article was just what I found that mentioned setting up Tunnelbroker with a dynamic IP.
