@Paddy66 it depends.
I host everything, including website and email server behind a regular dynamic ip for years.
And no I don't get block by any gafam.
But I am lucky because my ISP doesn't change that often (maybe twice a year). And my domain provider provides an API that my ISP router can use to update my IP automatically.
It may work, it may not :)
@puck I don't know shit about macos, but if it was me, I would ditch macOS for sure (i least I'd try).
@puck if your not using your mac for any other purpose you may stick with it to see how it compete.
Even with a lot of services running, most of the time you don't need very high end cpu, especially if you can enable hw acceleration (like for jellyfin). In that scenario a 200$ power efficient small linux server might be enough (like N15 trigkey). What will cost you money is memory.
Don't forget you need to buy backups disks (or use the ones you already have).
@hono4kami To me, good documentation is the number one thing that makes a selfhostable application good.
Second would be "is it dockerized ?"
@curry after i setup everyrthing I had no deliverability issue. But i had to use an external SMTP relay because of my isp filtering traffic on port 25. That adds an extra fixed IP layer that may provide a better IP reputation idk. I rent a cheap 1.2€/month vps for that purpose.
I get listed in spamhaus because of a dynamic IP, but my relay isn't listed (at least not in not scam blocklist). Anyway I send mail, to gafam or whatever and people reply back.
I send 2-3 mails a week, maybe it counts.
