If you have multiple servers on a network, do you install postfix on each one

So, in my attempt to just dummy down this whole thing.
I was just saying if you send from dnf-automatic to public servers, it will not e-mail the server, be accepted by the server, and then delivered to your inbox without some work.
So far, in using postfix, I have not had any of these issues. Install postifx, works perfectly.
/sigh FFS

We've all been talking about email (SMTP), but @BRRABill is actually wanting to ask questions about post-email mailbox filtering and approval by specific hosted services vendors. Which is not really about email, but about working out how to identify SPAM after it has been received.
Mixing those two concepts together as if they are one will always lead to massive confusion and a misinterpretation of events.
Yes...
I used the phrase "dnf cannot e-mail me at gmail"
when the correct @scottalanmiller phrase is
"dnf cannot email me at gmail, have it accepted by gmail, and then delivered into my inbox by gmail"

Of course it can. You need to stop saying things "can or can't" because we will FFS every one of those.
Everything works. All of it. You just have to set it up to do so.

The reason postfix is working for you is because you are sending via postfix directly, postfix is the relay. Your dnf-automatic I'm guessing you have told GMail to be your relay but haven't worked this out with GMail. So they are denying you relay access.

Only one person here will.

dnf-automatic acts as a client, not an MTA, even though it has SMTP. So it is attaching to whatever server you are telling it is the relay and trying to relay through it. If you haven't told the server in question to accept relay access, it will fail. If you tell it to accept access, it will work.

Remember, Jared was telling you that with dnf-automatic that you still needed postfix, but not one postfix PER SERVER. Postfix is the relay that will work. If you want to send with zero postfix, then you need to get Google or whoever to be your relay and they have to agree to that.
The original thread is one postfix per network or one per server. If you use mailx, you need one per server. If you use dnf-automatic, you need one per network (but one per server works, too.) In both cases, GMail can't tell the difference.

Oh FFS, now we need to know blackmagic too!
