taquiones.net is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
Was wondering if anyone knows this MTA (Stalwart) or has experiences with it. Found it totally randomly, never heard of it before despite knowing quite a bit about mail subsystems, and if the docs are correct, it's the kind of too-good-to-be-true software. Pure Rust and brings everything onboard (at least I) need.
is there any VPS provider more chad than #Contabo ?? https://arcanechat.me VPS went down today, the VPS will simply fail to start from the Control Panel, this WAY TOO OFTEN happens during weekends or holidays, their status page says nothing about any problems or maintenance, and if you try to write to support they will tell you "sorry it is weekend, your message will not even be stored" so I guess arcanechat.me will be down the whole weekend >:-/
I sent my first #email msg through #gmail on Sep 13, 2004. We're more than 20 years later now and it's time to move on.
I registered my own domain this time and I'm looking at alternatives like @fastmail , @Tutanota , @protonprivacy, and @mailfence .
It's good to see that they all have mastodon accounts, although not all of them seem active anymore?
If anyone has another good suggestion then please let me know!

#Tuta: one month free trial to celebrate #WorldQuantumDay
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.

The #ThunderBird project is launching pro services to help fund development;
"It is our goal to eventually have a similar offering so that a 100% open source, freedom-respecting alternative ecosystem is available for those who want it. We don’t even care if you use our services with Thunderbird apps, go use them with any mail client. No lock-in, no restrictions – all open standards. That is freedom."

My blog post on #NNCPNET, the #email network atop #NNCP : https://changelog.complete.org/archives/10768-announcing-the-nncpnet-email-network
@jeremiah_ @elb #NNCPNET, the new #NNCP-based email network, now has a bidirectional, opt-in, Internet #email bridge! https://salsa.debian.org/jgoerzen/docker-nncpnet-mailnode/-/wikis/bridge/intro
This gates Internet email to/from NNCP. The bridge is off by default. It is a full participant in #SPF, #DKIM, #DMARC, and #TLS in both directions.
Yes, now you can get Internet email straight to your #RaspberryPi ! (And even without this, your Pis can email each other!)
Fuck #Google and the garbage imitation of IMAP that they foist on users & fuck their #SecurityTheater of demanding CASA audits of every IMAP client before they allow it to do OAuth2.
If you use #GMail (or Google Workspace) you are actively supporting the enclosure of #email. Google does not want independent standards-compliant MUAs to touch their mail system. Google wants all of its users using their shit web interface or their shoddy apps. They want to own your email.
"Google is updating Gmail to allow enterprise users to send encrypted messages to any inbox in just a few clicks. Google says it’s developed a new encryption model that, unlike the current encryption feature on Gmail, doesn’t require senders or recipients to use custom software or exchange encryption certificates.
The feature is rolling out in beta starting today, and will initially be available for Google enterprise users to send encrypted emails to other Gmail users within the same organization. Google says this will expand to emails sent to any Gmail inbox “in the coming weeks,” and to inboxes from any third-party email provider “later this year.”
Gmail’s current encryption feature, based on the Secure/Multipurpose Internet Mail Extensions (S/MIME) protocol, can already be used to send external emails. Doing so requires the recipient to have S/MIME configured and complete multiple steps with the sender before emails can be securely exchanged, however."

I said it before on Mastodon. I'm reposting this again. Comparing #DeltaChat and #Matrix together, if you want hassle free and consistent messenger for private #E2EE chats, don't go for Matrix. DeltaChat is way better.
However, if you want something like a public forum, or a public chatroom, don't go for DeltaChat. Matrix is way better suited for that. And DeltaChat does not support public groups at all. In DeltaChat groups, there is no admin or moderator and everyone have got permission to remove or add the others.
I think I have to write a longer post on my personal blog about these two, comparing them together.
PS: Another Matrix encryption bug few minutes ago triggered repost of this.

I thought I had seen it all when it comes to mail delivery and security issues.
But this morning I was introduced to the fact that there are Exchange admins who will implement a rule that all incoming mail from outside their own organization should be flagged as potentially dangerous and presented to the user with the option to block sender and no option to mark the message or the sender as valid.
Yes, that for every single message.

#Tuta’s diverse team keeps growing in 2025! 🥳❤️
We are not aware of other FOSS development teams that have as extensive knowledge, both theoretical and practical, about #email and #openpgp and regularly release across all platforms for users world wide ... except for #protonmail with whose technical and security experts we discuss regularly. They are the other major game in town doing pervasive email encryption after all. Did you know that Proton's and delta's VCards are compatible across ecosystems and establish immediate encryption?

#India: Your #email and #SocialMedia account can be accessed by income #tax officers starting financial year 2026-27 in these cases
Not sure which e-mail provider to go for? 📩
Most of them offer free accounts to get you started.
Just create an account and have a play around with the interface. Check all the settings and filter options to see what they offer. Send yourself an email from your current inbox to see how it looks and how long it takes to arrive.
And remember, there are full teams working to build these products. It costs money. A lot! 💰
Imagine being on their team, really happy with every new client that's come from a competitor. 🥳
Gmail was launched in 2004. It took 20 years to get to where it is now.
Give a chance to little tech companies that are trying hard to build a modern ethical alternative without having illegal revenues like Google. They need money to pay developers, devops, security team, project managers, analysts, designers, audits, HR and marketing teams, accessibility experts, etc. It's expensive to hire professionals who can go fast, safe and scale.
Building digital products is hard, complex... and beautiful. 😍
Give them a chance to thrive. They need consumers and followers. Don't attack them if a button isn't working. Send them constructive feedback.
And if you like it after testing, you can always recommend them to your family, friends and followers. 😉

@tk @ezmyrelda @feld our general approach is that we only use a reasonable *subset* of the standards. Both #email and #OpenPGP specifications contain a lot of flexibility that has caused many past projects to drown in complexity. We avoid that by thinking about and steering developments starting from the desired UX/UI we want to offer. UX/UI-first if you will ;)
@lns 99.9% of my email communication is e2e encrypted, I am using #DeltaChat since years, never managed to actually use encrypted email in any other way, ex. why should my mom learn how to use GPG? meanwhile she and several family members that are new to phones are sending #encrypted #email to me every day without even realizing it

I have heard some people argue for moving away from Web-based social-media and returning to E-Mail for their social-media distribution needs.
I think a lot of people don't realize how difficult it is to do something as simple as sending out an e-mail -based newsletter.
There are a lot of hurdles in the way of your e-mail newsletter getting delivered to your subscribers.
E-Mail doesn't remove the gatekeepers or middlemen. It just replaces them with Google GMail, etc

Just saw someone floating around the idea of charging email subscribers, but keeping your RSS feed free. I’ve never thought about it before, but an email list actually does cost money to run, and if you really don’t want to take the time to learn how RSS works, then you need to pay to keep the mailing list alive. I don’t know how I feel about this. On the one hand, it limits people that aren’t very technology savvy and it capitalizes off of their technology ignorance enough but on the other, RSS is free for us creators. An email list is not. #Email #Newsletter #MailingList #RSS
Isn't it poetic and ironic that out of all possible time lines we are in one where #securejoin #openpgp protocols on top of the existing #email protocols offer the arguably most solidly scaling, useable, world-wide federated end-to-end encrypted messaging reality, safe against compromised #mitm servers? Hundreds of billions spend to create "the email successor" and here we are in 2025 .... #interoperable #email and #cryptography as the tortoise looking at Achilles through the back mirror :)
someone told to me that now you can get a @signalapp with email and the tel number is not necessary.
i have searched but i din't find it.
do you know if it is real?
Do you use a custom domain name for your email address?
Have you noticed any additional difficulties with using newer top level domains compared to the old traditional ones? Or has it made no difference whether you use newer or older TLDs?
(Newer TLDs would be things like .social or .pizza or .world, older TLDs would be .com or .org or .net)
Asking as there seem to be conflicting reports about how much email is affected by the choice of TLD?
@nick_appleyard @shojiwax Consider registering your own domain name apart from an #email provider’s domain name. It's a little upfront work and periodic expense, but saves time and hassle when switching.
#ProtonMail’s custom domain hosting is $3.99 a month if you pay yearly, includes 15 GB of storage and 10 addresses, and a calendar: https://pr.tn/ref/0Z7R6D2AX92G
#TIL that #Thunderbird lets me set #filters to move an #email to a particular place *when* I archive it, rather than immediately! So I can still read the emails as they come in, and then hit "archive" to have them automagically filed away 📁️
There are other triggers too, besides "as soon as the email comes in" and "when I archive" that I haven't explored yet. Thunderbird rocks! ✨️

* You can find my key at https://gpg.gyptazy.com and you're allowed to upload them to key servers.
