#ryoms — Public Fediverse posts

Also trying to simultaneously use Postfix in multi-instance mode, which is not covered in #RYOMS, but if something is worth doing it's worth overdoing, I guess.

Running Modoboa as you mailserver?
Need/want to migrate to a new instance?
Want to keep mailboxes and configs, but otherwise have a clean "new" install?

@r Polished my setup a bit. Everyone’s happy except Outlook.com. So there’s absolutely no actionable intelligence in that report, or is there?

The 00s called and want their open relays back…(this is unfiltered back-to-back mail-log)

#ryoms

I've enjoyed following @rfcs. It's a steady reminder of the history I've lived through, what came before me, and alternate histories not taken.

But it just threw RFC 3463 at me, and: TOO SOON, BOT, TOO SOON. #ryoms

I’m seeing tons of the following in the mail-server logs. Anyone know what’s up there? Just the usual or a Xmas-special?

sm-mta[215926]: [45.148.10.25] did not issue MAIL/EXPN/VRFY/ETRN during connection to MSP-v4
sm-mta[215930]: [45.148.10.29] did not issue MAIL/EXPN/VRFY/ETRN during connection to MSP-v4
sm-mta[216460]: [178.16.55.124] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA-v4

@nixCraft Sounds like a good opportunity to Run Your Own Mail Server 😉

@whitequark Tagging this as #ryoms.

Google is back on this again with 37 identical DMARC emails today.

They’re definitely separate transactions from their SMTP and it looks like everything is being handled appropriately.

They just really like sending me DMARC messages.

Does this happen to anyone else?

#homelab #selfhosted #ryoms #email

I successfully put #OpenDKIM onto a production #Postfix server today and started signing the messages that Hotmail, et.al. were rejecting, and it took me less than half a day!

But I'm still going to tell my boss I want to buy a copy of #RYOMS and get reimbursed for it.

The #BSDCan Travel Fund auction in honor of Mike Karels ends today at 5PM EDT.

If you wanted a #RYOMS challenge coin or the special backers-only edition, this is your chance.

From the ISP I’ll be getting my ‘net from soon:

“RevDNS? Yeah, sure, we can do that, although I’ll have to ask the boss about pricing. No one ever asked us for such a thing, and our partner company got only 2 such cases since starting in 1992.”

I blame @mwl and #RYOMS for becoming a once-in-a-decade oddity. :blobfoxmelt2:

@jef Tagging this for #RYOMS

Hearing from more and more #sysadmin folks that the big mail providers are getting so bad that they're unwillingly reading #ryoms to set up their own mail systems.

Kind of a mixed blessing for me. What should I say? "I'm sorry you're going through this, but thanks for the money." "Told you so." "Welcome to suck less."

So I go with "good luck." Because none of us like this.

Critique de « Run Your Own Mail Server » (5 étoiles) : best email how to i've read

https://bw.heraut.eu/user/ludovic/review/26666

Any one running their own mail server? I've just received a copy of Run Your Own Mail Server by @mwl
I can't wait to try it out and see how it goes. I hope it will be a lot of fun! Hopefully not too many troubles 😅
I'm currently using Proton services with my own custom domain.
#ryoms

After much waffling and mucking, I finally have a functional mail server.

Still a few more things to finish up, but it's coming along. Even with #RYOMS, it can be quite the process. I tried testing out some of the AIO solutions, but kept running into trouble with those as well. Between the book and the LinuxBabe tutorials, things have been working well, if a bit time consuming.

#SelfHosted #SelfHosting #Email

Seeing quite a few people get bit by spamhaus blocking more shared resolvers today. It seems to not just be Hetzner addresses.

If you're having trouble with all your email rejected you too may be seeing the same issue.

My server is seemingly unaffected because I'm running my own recursive resolver (thanks to the Run Your Own Mail Server advice from @mwl) but I'm going to continue to monitor.

#selfhosted #email #RYOMS

Since I'm currently reading #RunYourOwnMailServer #RYOMS, the part about #DKIM reminded me about something I heard some time ago, and I managed to find it again. Concept somewhat similar to what #OTR does.

With greetings and thanks to @mwl and @ryanc 😅

#email #mail #security #privacy

I'm reading #RunYourOwnMailServer #RYOMS by @mwl , and I'm thinking about what I know so far about #stalwart https://stalw.art/, and I can't figure what his opinion of it would be, I can see it going either way 😅
- "oh, nice, don't need to need with all those separate things and making them talk to each other"
- "eh, if it works for you, cool, I already have mine 🤷"
- "this abomination doesn't even follow Unix philosophy, I wonder what else it does wrong - no, I don't want to know"

Received some goodies from @mwl
Consider me lost for a few weeks!

Many systemd-based systems handle Postfix services poorly, so you’ll want to use 'postfix' rather than 'systemctl'.¹¹
