== HOW TO SET UP ON THE DECENTRALISED FEDERATED SERVICE "E-MAIL" IN 2023 ==

1. your problem is Google, MS and Yahoo.
2. SMTP over SSL *only*.
3. SPF, DMARC, DKIM
4. they don't like your IP or your face or can't be bothered or something and you have weeks of supplication hoping there's a human there
5. give up and outsource it

as a sysadmin, I always advise going straight to step 5

anyone using "e-mail" as an example of a successfully decentralised federated service in 2023 does not know what they're talking about and should be ignored

stop doing this

EDIT: if you're a fatuous dipshit, read the replies before you answer. or better, don't.

@davidgerard pretty much gave up on it professionally in 2013. After more than a decade of massaging milter/sendmail or convincing an exchange server to unfuck its information store I tapped out
@davidgerard and don't get me started on domino/notes
@oxyhyxo i remember sendmail.cf, postfix is hauntingly simple by comparison
@davidgerard Slackware came with sendmail by default and it stuck lol

@oxyhyxo debian/ubuntu postfix is a delight

pity about the big three

microsoft was actually the worst to get a human at, we were a gapps customer with an account manager so could ask him to push it along

@davidgerard oh don't get me wrong I loathe the big cloud email providers. It was more me admitting defeat and submitting to the void

@davidgerard I've had some corkers with microsoft 365 support. Mailboxes just disappearing, support being unable to tell me anything. Pushing it along through the acct mgmt channel, nothing. Then the mailbox just magically reappears.

No postmortem, no-one can tell me why. Magical stuff

@oxyhyxo @davidgerard It's finally Postfix in 15.0.
@davidgerard @oxyhyxo Exim is p. good
@jeeger @davidgerard I've been dabbling with the idea of self hosting again - just have to get past the wave of fatigue that sets in at the thought
@oxyhyxo It's nice when you can get it working exactly the way you want.
@oxyhyxo @jeeger god i never want to host things
@davidgerard @jeeger I'd never recommend it professionally
@oxyhyxo @davidgerard
Notes was absolutely great in 1997-9 when my team only had occasional access when travelling around Europe. The asynch just worked.
Wouldn't use it now though...
@AlisonW @oxyhyxo i refuse to believe that Notes was at any point ever great. it did inspire me to write this though https://en.uncyclopedia.co/wiki/Lotus_Notes
Lotus Notes

@davidgerard @oxyhyxo
Yeah, well, we did need a permanent member of staff just to manage the notes install for us. We had a niche usecase which meant it was a suitable product, I doubt it was for others.
