Note

Sometimes the version shown on your host may be higher than the newest version here. In this case we might have applied additional fixes shortly after a release or did internal changes without user impact. We deem updates like these hotfixes and they are not necessarily included in this changelog.

[7.17.3] - 2026-04-28

We gave our spam filter a massive update to fend off spam even more reliably while ensuring legitimate emails pass through smoothly:

Added

  • The spam filter now uses an intelligent reputation system. It tracks the historical behavior of IP addresses and domains (if validated via SPF/DKIM). Reliable senders build a good reputation over time and pass through the filter more easily, while suspicious senders automatically lose trust.

  • We are now using the allowlists from dnswl.org. Senders known for exclusively sending legitimate mail receive a bonus. This noticeably reduces so-called “false positives” (legitimate emails incorrectly marked as spam).

Changed

  • We optimized, reactivated, or re-weighted the integration of various renowned blocklists (RBLs) - including Spamhaus, SpamCop, and Spameatingmonkey. We also made some under-the-hood DNS adjustments to ensure these lists are queried even more reliably.

  • Our own internal mailgates are now exempt from greylisting. This ensures faster, delay-free delivery for internal forwards.

  • We massively expanded our internal tools. As a team, we can now react much more granularly and quickly in the background to acute spam waves and maintain our own targeted filter rules.

[7.17.2] - 2026-02-12

Added

  • rspamd: Integrated commercial fuzzy database for SPAM mitigation

Fixed

  • Web: “unknown domain” errors now appear when there’s a path in the URL

  • Sieve can send emails without a sender (useful for rejects) again

[7.17.1] - 2026-01-30

fixed

  • prevent Haraka from asking for client certs to to (finally!) tackle the Thunderbird issues

  • set mail limit to 60 mails per hour, 200 recipients

[7.17] - 2026-01-16

Since the rollout of 7.17 didn’t go as planned, we are re-releasing it with some additional changes.

As we’re getting ready for Uberspace 8 beta we’re of course still working on Uberspace 7. Version 7.17 is more of a maintenance release for your and our peace of mind, here you go:

Added

  • PHP 8.5

Changed

  • We updated our mailserver Haraka to 3.1 to (hopefully!) tackle the Thunderbird issues.

  • We now enforce the mail limit of 60 mails / hour. Enjoy, spammers!

  • We reboot our servers now automatically under certain conditions. This is nothing new per se, we just did it manually until now.

  • Modern Ciphers (chacha20-poly1305@openssh.com,aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr), KexAlgorithms (curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256) and MACs (hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512,hmac-sha2-256)for sshd.

Fixed

  • files in /var/lib/php-sessions now have a maximum age of 7 days

Check your server’s login message to see if you’re already on 7.17. The rollout should be completed by the end of week 4, 2026.

[7.16.9] - 2025-09-22

Added

  • Erlang 27 and Erlang 28

  • added openssl11-devel for compiling

Changed

  • smtp limits for unfinanced accounts
