Wow, I didn't know there was so much piracy on Android. At least much more so than on desktop computers (or Windows specifically I guess). Enough to make a dev stop even, not just the usual "oh no a few people are pirating our software that would otherwise not have bought it anyway". I assumed it would be a relatively small percentage of more experienced users.
By mid-September, the iA team claimed to have spent five months making 55 updates to its app and privacy policy and was ready to scan its passports and verify its payment accounts.
Google then requested a CASA Tier 2 assessment. This needed to be done annually, either through an intensive self-directed process or through a corporate partner, like TAC Security or KPMG. By iA's estimation, the labor and fees to do this would cost "one to two months of revenue" for "a pretty much meaningless scan,” iA suggested in its post.
This is just absolutely crazy. I feel like Google absolutely had it out for them because why would they make them go through this arduous bullshit process for what seems to be described as a text editor app here.
But giving up Factorio is a bridge too far.
Factorio has an ARM port, it runs great on my M2 MacBook. But even if it didn't, Rosetta works well enough so that x86-only games are playable.
Okay, there are two different issues here. First, the mail delivery.
You have
and getting
This means that received mail is addressed to a domain that is not configured for local delivery, and the mail server is not accepting it to be relayed to the actual target server. This is a good thing, you do not want to have a public relay under any circumstances because it would mean people could make your server launch spam anywhere.
As for why it's not configured to accept that domain for local delivery, you need to look at the mydestination setting:
(from postconf(5).)
You left it at the default value, so it will accept mail addressed to mail.domain.com, localhost.domain.com, and localhost. You'll probably want to set that to additionally contain $mydomain (at least that is how mine is configured).
Also, something else:
You'll want those to match up, system hostname and postfix's myhostname, since you'll need to set the PTR record of your IP to match the hostname your SMTP server identifies itself as, and otherwise your server's IP resolves to mail.domain.com while the canonical hostname is domain.com. It will work for mail, it'll just not be nice when your server's IP resolves to mail.domain.com for stuff that isn't mail and that isn't the canonical hostname. I recommend giving it some other hostname (or just setting both to mail.domain.com if the system just handles mail).
