It's definitely going to go to spam since there's no SPF record. You'll need to manually whitelist that address on the receiving end.
Cannot find it in my spam-folder either, and with the mailutils
mailI set also set the-r $emailFromto something that is whitelisted in my spamfilter. But maybe my mail-service provider has some other block. Could that be? Or that it looks very fishy with an e-mail with only from, to, and subject headers non-empty?You've initially said you wanted to receive it locally only. Now you're pulling external email providers into the mix. You need to set up spf and dmarc for that at the minimum. I can help you with it, but it's nowhere near as simple as just emailing a local user.
Sorry, I must not have explained myself very well. I guess it is the part on receiving on localhost. What I meant to say was that I would like the smtp, or whatever, to only be available on localhost, so that no one else on the network can use the service to send e-mails.
Postfix can be configured to only listen on localhost. Most things can be, actually.
Ah, postfix looks like what I'm looking for, thanks. Have to see if I can figure out how to configure it.
ArchWiki, as always, is amazing.
You definitely don't need dmarc for that. Don't even need dkim, really.
You are technically correct.
