Happy 20th Anniversary, Gmail. I'm Sorry I'm Leaving You
* [1] should be https://stalw.art
It's a neat project though, that I hadn't heard of before. I have ran Postfix to do domain-wide email forwarding (to Gmail coincidentally) but going the other way around and having the end destination be self hosted is on my to-do list.

Also take a look at Stalwart: https://github.com/stalwartlabs/mail-server
I haven't used it, but have used some of the sub-crates for some email-parsing problems, and it worked great.

I made a tool for automatically updating the current and next (rollover) TLSA DNS records with acme.sh and the Cloudflare API
Yes, still using Maddy + Dovecot + Rspamd and everything works fine, but I've been thinking about trying out https://stalw.art/ to be able to try out the new JMAP protocol that is intended to replace IMAP.

Self-hosted ProtonMail alternative: Encryption at rest with S/MIME or OpenPGP now available in Stalwart Mail Server
Excited to announce that Encryption at Rest has just been added to the open source Stalwart Mail Server. With this addition, the mail server will now automatically encrypt all incoming plaintext emails, utilizing either OpenPGP or S/MIME, before they are written to disk. Importantly, the keys are owned and controlled by the end user, ensuring that not even system administrators can decrypt these messages. More details available in the documentation.

Setting up a Homelab: Part 1 Proxmox and LetsEncrypt
A self-signed certificate was generated and used by Proxmox which will always generate a warning on the browser. I did not like seeing this when trying to work on my home lab. So, I started looking for ways to put a valid SSL certificate in Proxmox. During my research, I found that Proxmox could be made to integrate with acme.sh; a free SSL certificate generator powered by ACME(Let's Encrypt).

How to Build Email Server with Exim on Alma Linux 9
Next, we will install acme.sh, a command-line tool for managing SSL/TLS certificates. I prefer acme.sh over certbot, as it does not depend on the OS version. For more details about acme.sh, check its GitHub repo here.

Dehydrated: Letsencrypt/acme client implemented as a shell-script
A very relevant question. Acme.sh, a similar shell script ACME client, had a remote code execution problem last year.

Ask HN: What is your experience with ZeroSSL?
As a result, any certificates issued (or renewed) after Feb 8th will not work on older Android devices (< 7.1.1), unless the ACME client has been configure to request an alternate certificate chain. The "alternate chain" workaround will also stop working on June 6th.
I need to support these older Android devices so I am looking for alternatives. I have seen ZeroSSL mentioned a few times; it is also the default CA for acme.sh (the ACME client I am using nowadays) [2]. They have a number of paid plans but ACME certificates are free [3].
I'll be testing this over the next few days, but I would also like to ask if people here have experience with ZeroSSL (good or bad :-). Any feedback would be helpful.

Why Certificate Lifecycle Automation Matters
Huh, the environment variable thing was specifically aimed at acme.sh which rather arbitrarily changed the config value from ACMEDNS_UPDATE_URL to ACMEDNS_BASE_URL, never acknowledged this in a changelog and then silently failed after an automatic upgrade as recommended by the default install:
https://github.com/acmesh-official/acme.sh/commit/2ce145f359...
It's also cleared out my .account.conf files when run on the suggested cron.
I've started using updown which also monitors my TLS certs simply because I no longer trust the process to work as documented.

The Bureau of Meteorology website does not support connections via HTTPS
It depends on your provider though. I can tell from experience that with OVH and their API, it's been easy to set up the automatic renewal via DNS verification. Apparently, the official client has support for the DNS API of 159 providers: https://github.com/acmesh-official/acme.sh/wiki/dnsapi

I made a tool for automatically updating the current and next (rollover) TLSA DNS records with acme.sh and the Cloudflare API
For the few people here that happen to run a self-hosted email server with acme.sh for TLS key/cert generation and Cloudflare for DNS management, I have made a tool that i personally use to get a perfect 100% score on Internet.nl's email test.

How to get LetsEncrypt certs from PfSense/ACME to other machines? (automated??)
All of this is to say it's a decent amount of work to save the hassle of deploying certbot or acme.sh on the remote machines, pick your poison.

This is Fine
People wonder why I like using the shell-based ACME client like dehydrated (or acme.sh):
* https://packages.debian.org/search?keywords=dehydrated
* https://github.com/acmesh-official/acme.sh
Versus the official client certbot:
* https://packages.debian.org/search?keywords=python3-certbot
A kludgy as very long shell scripts are (thought to be), I have a better chance of being able to go through all the code and understand it than a dozen(+) Python libraries.
What are some alternatives?
jmap - JSON Meta Application Protocol Specification (JMAP)
letsencrypt - Certbot is EFF's tool to obtain certs from Let's Encrypt and (optionally) auto-enable HTTPS on your server. It can also act as a client for any other CA that uses the ACME protocol.
