Erm, fellow mailserver hackers: did I miss something?
I was just told that I should use SHA256 hashes, rather than SHA512 for MTA DANE (meaning: eg 3 1 1 rather than 3 1 2).
Is this correct? I fail miserably at finding the corresponding RFCs.

Back in 2006 I wanted to self host my mail. After two weeks of feeling with a bunch of howtos from the linux documentation project I gave up. That was also probably due to me getting free email hosting from google. When that offer ended, I thought about self hosting again , this time documentation was way better. This book is huge howtos and covers everything email related. The protocols, the history. It also provides exemples, sequencing : what to do first and then. I've been using email and managing some email related domains for 25ish years. I've learned a lot and would recommend that every sysadmin reads this book.

New blogpost: "Configuring dovecot as a separate mail server for encrypted email storage, and fighting with Thunderbird to accept it"
I woke up far too early this morning, so I thought I'd write up a small project I undertook a few months back, as part of my decoded.legal ISO-27001-ish programme.
It was pretty straightforward, right up until I had to fight with Thunderbird, and wow was Thunderbird a complete pain here. But I won!

The Craig Maloney Memorial Auction in support of Mutual Aid Disaster Relief ends tonight.
Craig sponsored "Run Your Own Mail Server." His widow is allowing me to auction off his sponsor gift for charity.
Bid now at https://mwl.io/archives/23810 . I'll take last-minute bids during my mug.org talk tonight, then close the auction.
Oh, yeah. I'm talking #ryoms at tonight's mug.org meeting, online. Details at https://www.mug.org/2024/09/mug-meeting-tuesday-oct-8-2024/
A preemptive blog post:
Why "Run Your Own Mail Server" will not be in Amazon's Kindle store.
You can get Kindle-friendly versions, no problem. But not from Amazon.
Patronizer copies, sponsor gifts, and Kickstarter signed special editions heaped up for shipping. #ryoms
The mail dude is gonna swear a blood oath against me.
I've been running mail servers and writing email software since the dialup days of 1995. I guess by today's trends, that could brand me a holdout.
But we're still hosting mail for hundreds of company domains across dozens of mail servers, all in a nicely packaged system that's always just an "apt install" away.
The landscape has changed over time, and, yes, it is annoying dealing with the imbalance that the behemoth mail providers represent these days.
But there's a lot to be said for not bargaining away your digital autonomy.
I saw @mwl selling his "Run Your Own Mail Server" book and jumped to pick up a copy. Not so much because I had a need for it (though it'll be interesting to compare notes!), but because I strongly support the idea that email is still a shared ecosystem and love that Michael is sharing the knowledge to ā¦

Long live the open Internet.
Reading @mwl's Run Your Own Mail Server #RYOMS reminds me of that time I tried to cook new dishes from the recipes of a famous chef. The recipe would contain an innocent sentence like "cut a chinese cabbage" and I would start wandering my favorite super market with the images found on the web (what does a chinese cabbage look like?) Arriving home with a cabbage, I would wonder: which part of this cabbage can I eat? In how many parts should I cut the cabbage? What knife am I supposed to use?

The "Run Your Own Mail Server" kickstarter is less than $2000 from a $65,535 buffer overflow.
Right now, all backers get "Run Your Own Mail Server," "Networking for System Administrators," "$ git commit murder," "Ed Mastery," "PAM Mastery," "Sudo Mastery," and assorted tidbits.
If the campaign overflows, I add "SSH Mastery" to that list. And have to add a new "loss of authorial dignity" reward.
