For full details see the [releases page](https://mailu.io/2.0/releases.html)
Upgrade should run fine as long as you generate a new docker-compose.yml file and mailu.env file via setup.mailu.io.
After that any old settings can be reapplied to mailu.env.
Before making any changes, carefully read the [configuration reference](https://mailu.io/2.0/configuration.html). New settings have been introduced and some settings have been removed.
Multiple changes have been made to the docker-compose.yml file and mailu.env file.
If you use Fail2Ban, then the Fail2Ban intructions have been improved. It is mandatory to remove your Fail2Ban config and re-apply it using the instructions from the [documentation](https://mailu.io/2.0/faq.html#do-you-support-fail2ban).
Please note that once you have upgraded to 2.0 you won't be able to roll-back to earlier versions
After changing mailu.env, it is required to recreate all containers for the changes to be propagated.
2.0.0 - 2023-04-03

- Features: Added ability to mark spam mails as read or unread when moving to junk folder. ([#2278](https://github.com/Mailu/Mailu/issues/2278))
- Features: Switch from RainLoop to SnappyMail. SnappyMail has better performance and is more secure. ([#2295](https://github.com/Mailu/Mailu/issues/2295))
- Features: Configurable default spam threshold used for new users ([#2328](https://github.com/Mailu/Mailu/issues/2328))
- Features: Create a GUI for WILDCARD_SENDERS ([#2372](https://github.com/Mailu/Mailu/issues/2372))
- Features: Prevent signups with accounts for which an SQL-LIKE alias exists. ([#2429](https://github.com/Mailu/Mailu/issues/2429))
- Features: Introduce TLS_PERMISSIVE, a new advanced setting to harden cipher configuration on port 25. Changing the default is strongly discouraged, please read the documentation before doing so. ([#2449](https://github.com/Mailu/Mailu/issues/2449))
- Features: Upgrade the anti-spoofing rule. We shouldn't assume that Mailu is the only MTA allowed to send emails on behalf of the domains it hosts... but we should also ensure that both the envelope from and header from are checked. ([#2475](https://github.com/Mailu/Mailu/issues/2475))
- Features: Implement the required glue to make "doveadm -A" work ([#2498](https://github.com/Mailu/Mailu/issues/2498))

- Features: New override system for Rspamd. In the old system, all files were placed in the Rspamd overrides folder.
These overrides would override everything, including the Mailu Rspamd config.
Now overrides are placed in /overrides.
If you use your own map files, change the location to /override/myMapFile.map in the corresponding conf file.
It works as following.
* If the override file overrides a Mailu defined config file,
it will be included in the Mailu config file with lowest priority.
It will merge with existing sections.
* If the override file does not override a Mailu defined config file,
then the file will be placed in the rspamd local.d folder.
It will merge with existing sections.
For more information, see the description of the local.d folder on the rspamd website:
- Features: Adds a button to the roundcube interface that gets you back to the admin interface ([#2591](https://github.com/Mailu/Mailu/issues/2591))
- Features: Drop postfix rsyslog localhost messages with IPv6 address ([#2594](https://github.com/Mailu/Mailu/issues/2594))
- Features: Isolate radicale and webmail on their own network. This ensures they don't have privileged access to any of the other containers. ([#2613](https://github.com/Mailu/Mailu/issues/2613))
- Features: Improved IPv6 support ([#2630](https://github.com/Mailu/Mailu/issues/2630))
- Features: Provide a changelog for minor releases. The github release will now:
* Provide the changelog message from the newsfragment of the PR that triggered the backport.
* Provide a github link to the PR/issue of the PR that was backported.
Switch to building multi-arch images. The images build for pull requests, master and production
are now multi-arch images for the architectures:
* linux/amd64
* linux/arm64/v8
* linux/arm/v7
Enhance CI/CD workflow with retry functionality. All steps for building images are now automatically
retried. If a build temporarily fails due to a network error, the retried step will still succeed. ([#2653](https://github.com/Mailu/Mailu/issues/2653))
- Features: Add Czech translation for web administration interface. ([#2676](https://github.com/Mailu/Mailu/issues/2676))
- Features: Allow inbound to http and mail ports to accept the PROXY protocol ([#2717](https://github.com/Mailu/Mailu/issues/2717))
- Bugfixes: Add an option so that emails fetched with fetchmail don't go through the filters (closes #1231) ([#1231](https://github.com/Mailu/Mailu/issues/1231))
- Bugfixes: Allow '+' in the localpart of email addresses to forward to ([#1236](https://github.com/Mailu/Mailu/issues/1236))

It is used for the enigmail roundcube plugin. ([#2117](https://github.com/Mailu/Mailu/issues/2117))
- Bugfixes: Fix CI/CD workflow. Tags were not set to the correct commit hash. ([#2124](https://github.com/Mailu/Mailu/issues/2124))
- Bugfixes: Fix a bug preventing mailu from being usable when no webmail is configured ([#2125](https://github.com/Mailu/Mailu/issues/2125))
- Bugfixes: Enable unbound by default. Mailu now requires a DNSSEC validating DNS resolver and experience has shown that this may not be the default everywhere yet. ([#2135](https://github.com/Mailu/Mailu/issues/2135))
- Bugfixes: Pin the root certificate differently for DANE. If you have setup a TLSA record following previous suggestion from Mailu please update it. ([#2138](https://github.com/Mailu/Mailu/issues/2138))
- Bugfixes: Remove the misleading text in mailu.env that zstd and lz4 are supported for dovecot mail compression.
Zstd and lz4 are not supported. The reason is that the alpine project does not compile this
into the dovecot package.
Users who want this funcionality, can kindly request the alpine project to compile dovecot
with lz4&zstd support. ([#2139](https://github.com/Mailu/Mailu/issues/2139))

- Bugfixes: Disable the built-in nginx resolver for traffic going through the mail plugin. This will silence errors about DNS resolution when the connecting host has no rDNS. ([#2346](https://github.com/Mailu/Mailu/issues/2346))
- Bugfixes: Re-enable the built-in nginx resolver for traffic going through the mail plugin.
This is required for passing rDNS/ptr information to postfix.
Without this rspamd will flag all messages with DHFILTER_HOSTNAME_UNKNOWN due to the missing rDNS/ptr info. ([#2368](https://github.com/Mailu/Mailu/issues/2368))

- Bugfixes: Enable rspamd's autolearn feature to ensure that its bayes classifier has enough HAM to make it usable. Previously the bayes module would never work unless some HAM had been learnt manually. ([#2447](https://github.com/Mailu/Mailu/issues/2447))
- Bugfixes: Fix a bug preventing users without IMAP access to access the webmails ([#2451](https://github.com/Mailu/Mailu/issues/2451))
- Bugfixes: Ensure that Mailu keeps working even if it can't obtain a certificate from letsencrypt for one of the HOSTNAMES ([#2467](https://github.com/Mailu/Mailu/issues/2467))
- Bugfixes: Quote SMTP SIZE to avoid splitting keyword and parameter in EHLO response ([#2485](https://github.com/Mailu/Mailu/issues/2485))

- Bugfixes: Tweak the snuffleupagus rules to make roundcube's caldav work ([#2693](https://github.com/Mailu/Mailu/issues/2693))
- Bugfixes: Proxy authentication was using the real client ip instead of the proxy
IP for checking the PROXY_AUTH_WHITELIST. ([#2708](https://github.com/Mailu/Mailu/issues/2708))
- Improved Documentation: remove the / in the location to avoid http 404 ([#2185](https://github.com/Mailu/Mailu/issues/2185))
Upgrade should run fine as long as you generate a new compose or stack configuration and upgrade your mailu.env. Please note that once you have upgraded to 1.9 you won't be able to roll-back to earlier versions without resetting user passwords.
One major change for the docker compose file is that the antispam container needs a fixed hostname [#1837](https://github.com/Mailu/Mailu/issues/1837).
Please note that the shipped image for PostgreSQL database is fully deprecated now. To migrate to the official PostgreSQL image, you can follow our guide [here](https://mailu.io/master/database.html#mailu-postgresql)
- Features: Document how to setup client autoconfig using an override ([#224](https://github.com/Mailu/Mailu/issues/224))
- Features: Add support for timezones ([#1154](https://github.com/Mailu/Mailu/issues/1154))
- Features: Ensure that RCVD_NO_TLS_LAST doesn't add to the spam score (as TLS usage can't be determined) ([#1705](https://github.com/Mailu/Mailu/issues/1705))
- Features: Add support for ECDSA certificates when letsencrypt is used. This means dropping compatibility for android <4.1.1
Add LETSENCRYPT_SHORTCHAIN to your configuration to avoid sending ISRG Root X1 (this will break compatibility with android <7.1.1)
Disable AUTH command on port 25
Disable TLS tickets, reconfigure the cache to improve Forward Secrecy
Prevent clear-text credentials from being sent to relays ([#1922](https://github.com/Mailu/Mailu/issues/1922))
- Features: Improved the SSO page. Warning! The new endpoints /sso and /static are introduced.
These endpoints are now used for handling sign on requests and shared static files.
You may want to update your reverse proxy to proxy /sso and /static to Mailu (to the front service).
The example section of using a reverse proxy is updated with this information.
- New SSO page is used for logging in Admin or Webmail.
- Made SSO page available separately. SSO page can now be used without Admin accessible (ADMIN=false).
- Introduced stub /static which is used by all sites for accessing static files.
- Removed the /admin/ prefix to reduce complexity of routing with Mailu. Admin is accessible directly via /admin instead of /admin/ui
Note: Failed logon attempts are logged in the logs of admin. You can watch this with fail2ban. ([#1929](https://github.com/Mailu/Mailu/issues/1929))
- Features: Disable the login page if SESSION_COOKIE_SECURE is incompatible with how Mailu is accessed as this seems to be a common misconfiguration. ([#1996](https://github.com/Mailu/Mailu/issues/1996))
- Features: Derive a new subkey (from SECRET_KEY) for SRS ([#2002](https://github.com/Mailu/Mailu/issues/2002))

- Features: rspamd: get dkim keys via REST API instead of filesystem ([#2017](https://github.com/Mailu/Mailu/issues/2017))
- Features: updated roundcube to 1.5 and carddav to 4.2.2 using php8 ([#2035](https://github.com/Mailu/Mailu/issues/2035))
- Features: use dovecot-fts-xapian from alpine package ([#2072](https://github.com/Mailu/Mailu/issues/2072))
- Features: Make the rate limit apply to a subnet rather than a specific IP (/24 for v4 and /56 for v6) ([#116](https://github.com/Mailu/Mailu/issues/116))
- Features: Add instructions on how to create DNS records for email client auto-configuration (RFC6186 style) ([#224](https://github.com/Mailu/Mailu/issues/224))
- Features: Remove the Received header with PRIMARY_HOSTNAME [PUBLIC_IP] ([#466](https://github.com/Mailu/Mailu/issues/466))
- Features: Centralize the authentication of webmails behind the admin interface ([#783](https://github.com/Mailu/Mailu/issues/783))
- Features: Add sending quotas per user ([#1031](https://github.com/Mailu/Mailu/issues/1031))
- Features: Allow specific users to send emails from any address using the WILDCARD_SENDERS setting ([#1096](https://github.com/Mailu/Mailu/issues/1096))
- Features: Use semantic versioning for building releases.
- Add versioning (tagging) for branch x.y (1.8). E.g. 1.8.0, 1.8.1 etc.
- docker repo will contain x.y (latest) and x.y.z (pinned version) images.
- The X.Y.Z tag is incremented automatically. E.g. if 1.8.0 already exists, then the next merge on 1.8 will result in the new tag 1.8.1 being used.
- Make the version available in the image.
- For X.Y and X.Y.Z write the version (X.Y.Z) into /version on the image and add a label with version=X.Y.Z
- This means that the latest X.Y image shows the pinned version (X.Y.Z e.g. 1.8.1) it was based on. Via the tag X.Y.Z you can see the commit hash that triggered the built.
- For master write the commit hash into /version on the image and add a label with version={commit hash}
- Release shows a static message (see RELEASE_TEMPLATE.md) that explains how to reach the newsfragments folder and change the branch to the tag (x.y.z) mentioned in the release. Now you can get the changelog by reading all newsfragment files in this folder. ([#1182](https://github.com/Mailu/Mailu/issues/1182))
- Features: Add a credential cache to speedup authentication requests. ([#1194](https://github.com/Mailu/Mailu/issues/1194))
- Features: Introduces postfix logging via syslog with these features:

- Features: Log authentication attempts on the admin portal ([#1926](https://github.com/Mailu/Mailu/issues/1926))
- Features: AdminLTE3 design optimizations, asset compression and caching
The relevant fetchmail files are now retained in the /data folder (in the fetchmail image).
See the docker-compose.yml file for the relevant volume mapping.
If you already had your own mapping, you must double check the volume mapping and take action. ([#1223](https://github.com/Mailu/Mailu/issues/1223))
- Bugfixes: Ensure that the podop socket is always owned by the postfix user (wasn't the case when build using non-standard base images... typically for arm64) ([#1294](https://github.com/Mailu/Mailu/issues/1294))
- Bugfixes: Fix "extract_host_port" function to support containers with custom / dynamic ports ([#1669](https://github.com/Mailu/Mailu/issues/1669))

- Bugfixes: Fix roundcube environment configuration for databases ([#1831](https://github.com/Mailu/Mailu/issues/1831))
- Bugfixes: Alpine has removed support for btree and hash in postfix... please use lmdb instead ([#1917](https://github.com/Mailu/Mailu/issues/1917))
- Bugfixes: Webmail and Radicale (webdav) were not useable with domains with special characters such as umlauts.
Webmail and radicale now use punycode for logging in.
Punycode was not used in the HTTP headers. This resulted in illegal non-ASCII HTTP headers. ([#1952](https://github.com/Mailu/Mailu/issues/1952))
- Bugfixes: Ensure that we do not trust the source-ip address set in headers if REAL_IP_HEADER isn't set. If you are using Mailu behind a reverse proxy, please ensure that you do read the documentation. ([#1960](https://github.com/Mailu/Mailu/issues/1960))
- Bugfixes: Reverse proxy documentation has been updated to reflect new security hardening from PR#1959.
If you do not set the configuration parameters in Mailu what reverse proxy header to trust,
then Mailu will not have access to the real ip address of the connecting client.
It is very important to configure this when using a reverse proxy. ([#1962](https://github.com/Mailu/Mailu/issues/1962))
- Bugfixes: Fixed roundcube sso login not working. ([#1990](https://github.com/Mailu/Mailu/issues/1990))
- Bugfixes: The DB_PORT and ROUNDCUBE_DB_PORT environment variables were not actually used. They are removed from the documentation. For using different ports you can already use the notation host:port . ([#2073](https://github.com/Mailu/Mailu/issues/2073))
- Bugfixes: Ensure that webmail tokens expire in sync with sessions ([#2080](https://github.com/Mailu/Mailu/issues/2080))
- Bugfixes: Introduce SESSION_TIMEOUT (1h) and PERMANENT_SESSION_LIFETIME (30d) ([#2094](https://github.com/Mailu/Mailu/issues/2094))
- Bugfixes: Hide the login of the user in sent emails ([#1638](https://github.com/Mailu/Mailu/issues/1638))
- Bugfixes: SSO login page to webmail did not work if WEB_WEBMAIL=/ was set. ([#2078](https://github.com/Mailu/Mailu/issues/2078))
- Bugfixes: #2079 Webmail token check does not work if WEBMAIL_ADDRESS is set to a hostname.
#2081 Fix typo in nginx config for webmail port (10043 to 10143) ([#2079](https://github.com/Mailu/Mailu/issues/2079))
- Bugfixes: Alias, relay and fetchmail lists in the admin interface were missing the edit button. ([#2093](https://github.com/Mailu/Mailu/issues/2093))
- Bugfixes: Fix bug introduced by enhanced session management ([#2098](https://github.com/Mailu/Mailu/issues/2102))
This 2Gb does not entail any other software running on the box.
So in total you require at least 3GB of memory and 1GB swap when antivirus is enabled. ([#470](https://github.com/Mailu/Mailu/issues/470))
