Email provider news

Anyone need to go down this route? Sending would be less than 50 emails a day on average. Claude is recommending SMTP2GO, DNSExit SMTP Relay, Prolateral outMail, or MailRoute. There are other big companies like Amazon SES, Mailgun, Postmark, SendGrid, but these seem for marketing/transactional services, not email self…

Five years ago, on 3 October 2021, the first commit landed in a small repository called mail-parser. It was an e-mail parsing library written in Rust, and nothing more. Over the following five years it grew into a complete mail and collaboration server with JMAP, IMAP, POP3, SMTP, CalDAV, CardDAV and WebDAV, a spam…

Five years ago, on 3 October 2021, the first commit landed in a small repository called mail-parser. That e-mail parsing library became the seed of a complete mail and collaboration server, and today, after five years of continuous development, we are proud to announce Stalwart v1.0, the first stable release.

I recently set up Stalwart Mail Server together with Bulwark Webmail, and so far the webmail experience has been surprisingly good. I also discovered Bulwark Native for Android. From what I can see, it already supports most of the essentials: email, multiple accounts, notifications, contacts, calendar integration, and…

Open source works because it is a relationship that benefits both sides. Lately, a few actors have started treating Stalwart as something to feed on instead. This post explains what has been happening, why our test suites are moving to a private repository, why the license is not changing, and how the Enterprise…

Hej, I have setup five MX setups for five domains using Stalwart, all of them with automated DNS management. However I am struggeling with DKIM rotation. Management >> Domains >> domain1.de >> DKIM is set to Automatic DKIM management DKIM1 (RSA & ed25519) enabled DKIM2 (RSA & ed25519) enabled Version string:…

I built for our support team at the hosting company where I work. It generates a temporary email address, you send a message to it, and the site shows a mail health report. A lot of the code was AI generated, but I wanted to use Stalwart to get to know it better.

Sieve is the standard language for filtering email on the server. The rules people create to move newsletters into a folder, flag messages from their manager or answer automatically while on holiday are, on many servers, Sieve scripts, uploaded over ManageSieve or JMAP for Sieve and executed every time a message…

Running the latest 0.16.22 released today. I've added my production mail server as an Allowed IP under Settings | security | AllowedIPs and then I setup a rule in my exchange server for forward all my email to a mailbox i made for myself on stalwart.

Sieve has no statement for printing a value or writing to a log, so debugging a mail filter has long meant sending test messages and reading debug headers out of their raw source. Sievepad runs the Stalwart Sieve interpreter in the browser, inside the editor that powers Visual Studio Code, so a script can be written,…
