`v10.4.0`

This release upgrades our base image from Debian 10 to Debian 11.
There is also an important regression fixed for SSL_TYPE=letsencrypt users.

[fix] A regression with check-for-changes.sh introduced in v10.3.0 affected SSL_TYPE=letsencrypt, preventing detection of cert renewals to restart services (unless using acme.json) #2326
[improvement] Base image upgraded from Debian 10 Buster to Debian 11 Bullseye #2116
- Postfix upgraded from 3.4 to 3.5. Dovecot upgraded from 2.3.4 to 2.3.13. Python 2 is no longer included in the image, Python 3 remains (more information).
- yescrypt is now supported upstream as a password hash algorithm, docker-mailserver continues to use SHA512-CRYPT (more information).
[chore] Dovecot statistics service disabled #2292

`v10.3.0`

WARNING: This release had a small regression affecting the detection of changes for certificates provisioned in /etc/letsencrypt with the config ENV SSL_TYPE=letsencrypt, unless you use Traefik's acme.json. If you rely on this functionality to restart Postfix and Dovecot when updating your cert files, this will not work and it is advised to upgrade to v10.4.0 or newer prior to renewal of your certificates.

[fix] The Dovecot userdb will now additionally create "dummy" accounts for basic alias maps (alias maps to a single real account managed by Dovecot, relaying to external providers aren't affected) when ENABLE_QUOTAS=1 (default) as a workaround for Postfix quota-status plugin querying Dovecot with inbound mail for a user, which Postfix uses to reject mail if quota has been exceeded (to avoid risk of blacklisting from spammers abusing backscatter) #2248
- NOTE: If using aliases that map to another alias or multiple addresses, this remains a risk.
[fix] setup email list command will no longer attempt to query Dovecot quota status when ENABLE_QUOTAS is disabled #2264
[fix] SSL_DOMAIN ENV should now work much more reliably #2274, #2278, #2279
[fix] DKIM - Removed refile: (regex type) from KeyTable entry in opendkim.conf, fixes validation error output from opendkim-testkey #2249
[fix] DMARC - Removed quotes around the hostname value in opendmarc.conf. This avoids an authentication failure where an OpenDKIM header was previously ignored #2291
[fix] When using ONE_DIR=1 (default), the spool-postfix folder now has the correct permissions carried over. This resolves some failures notably with sieve filters #2273
[improvement] Warnings are now logged for ClamAV and SpamAssassin if they are enabled but Amavis is disabled (which is required for them to work correctly) #2251
[improvement] user-patches.sh is now invoked via bash to assist Kubernetes deployments with ConfigMap #2295

Internal

These changes are primarily internal and are only likely relevant to users that maintain their own modifications related to the changed files.

[chore] Redundant config from Postfix master.cf has been removed, it should not affect any users as our images have not included any of the related processes #2272
[refactor] check-for-changes.sh was carrying some duplicate code from setup-stack.sh that was falling out of sync, they now share common code #2260
[refactor] acme.json extraction was refactored into a CLI utility and updated to Python 3 (required for future upgrade to Debian 11 Bullseye base image) #2274
[refactor] As part of the Traefik acme.json and SSL_DOMAIN work, logic for SSL_TYPE=letsencrypt was also revised #2278
[improvement] Some minor tweaks to how we derive the internal HOSTNAME and DOMAINNAME from user configured hostname and domainname settings #2280

`v10.2.0`

You no longer need to maintain a copy of setup.sh matching your version release from v10.2 of docker-mailserver onwards. Version specific functionality of setup.sh has moved into the container itself, while setup.sh remains as a convenient wrapper to: docker exec -it <container name> setup <command>.
ONE_DIR now defaults to enabled (1).
For anyone relying on internal location of certificates (internal copy of mounted files at startup), the Postfix and Dovecot location of /etc/postfix/ssl has changed to /etc/dms/tls. This may affect any third-party user-patches.sh scripts that depended on this path to update certs.
The Let's Encrypt section of our SSL / TLS docs has been brought up to date.

[scripts] update setup.sh to now use a running container first if one exists #2134
[scripts] included setup.sh functionality inside the container to be version independent again #2174
[scripts] HOSTNAME and DOMAINNAME setup improved #2175
[scripts] delmailuser can now delete mailboxed without TLD #2172
[scripts] properly exit on failure (#2199 in conjunction with #2196)
[scripts] make setup.sh completely non-interactive for Podman users #2201

Security

Some internal refactoring and fixes happened this release cycle in #2196:

[improve] The Postfix and Dovecot location of /etc/postfix/ssl has changed to /etc/dms/tls
[improve] An invalid SSL_TYPE or a valid value with an invalid configuration will now panic, exiting the container and emitting a fatal error to the logs
[fix] An unconfigured/empty SSL_TYPE ENV now correctly disables SSL support for Dovecot and general Postfix configurations. A reminder that this is unsupported officially, and is only intended for tests and troubleshooting. Use only a valid SSL_TYPE (letsencrypt and manual are recommended) for production deployments
[fix] TLS_LEVEL=intermediate now modifies the system (container) openssl.cnf config to set the minimum protocol to TLS 1.0 (from 1.2) and cipher-suite support to DEFAULT@SECLEVEL=1 (from 2). This change is required for Dovecot in upcoming Debian Bullseye upgrade, to be compatible with the TLS_LEVEL=intermediate cipher-suite profile. It may affect other software within the container that relies on this openssl config, should you extend the Docker image #2193
[fix] Provide DH parameters (default: RFC 7919 group ffdhe406.pem) at build-time, instead of during startup. Custom DH parameters regardless of ONE_DIR are now only detected when mounted to /tmp/docker-mailserver/dhparams.pem #2192
[docs] Revise the Let's Encrypt section of our SSL / TLS docs #2209

Miscellaneous small additions and changes

[ci] improved caching #2197
[ci] refactored spam tests and introduced common container setup template #2198
[fix] update Fail2Ban wrapper to propagate errors to user #2170
[fix] Dockerfile sed's are now checked #2158
[general] Updated default value of ONE_DIR to 1 #2148
[docs] updated Kubernetes documentation #2111
[docs] introduced dedicated Podman documentation #2179
[docs] miscellaneous documentation improvements
[misc] introduced GitHub issue forms for issue templates #2160
[misc] Removed the internal mkcert.sh script for Dovecot as it is no longer needed #2196

`v10.1.2`

This is bug fix release. It reverts a regression introduced with #2104.

[feat] Added dovecot-fts-xapian (#2064)
[security] Switch GPG keyserver (#2051)

`v10.0.0`

This release improves on 9.1.0 in many aspect, including general fixes, Fail2Ban, LDAP and documentation. This release contains breaking changes.

[general] Fixed many prose errors (spelling, grammar, indentation).
[general] Documentation is better integrated into the development process and it's visibility within the project increased (#1878).
[general] Added stop_grace_period: to example Compose file and supervisord (#1896 #1945)
[general] ./setup.sh email list was enhanced, now showing information neatly (#1898)
[general] Added update check and notification (#1976, #1951)

[ldap] Complete rework of LDAP documentation (#1921)
[docs] PRs that contain changes to docs will now be commented with a preview link (#1988)

Breaking Changes

[security] Fail2Ban adjustments:
- Fail2ban v0.11.2 is now used (#1965).
- The previous F2B config (from an old Debian release) has been replaced with the latest default config for F2B shipped by Debian 10.
- The new default blocktype is now DROP, not REJECT (#1914).
- A ban now applies to all ports (iptables-allports), not just the ones that were "attacked" (#1914).
- Fail2ban 0.11 is totally compatible to 0.10, but the database got some new tables and fields (auto-converted during the first start), so once updated to DMS 10.0.0, you have to remove the database mailstate:/lib-fail2ban/fail2ban.sqlite3 if you would need to downgrade to DMS 9.1.0 for some reason.
[ldap] Removed SASLAUTHD_LDAP_SSL. Instead provide a protocol in SASLAUTHD_LDAP_SERVER and adjust SASLAUTHD_LDAP_ default values (#1989).
[general] Removed stable release tag (#1975):
- Scheduled builds are now based off edge.
- Instead of stable, please use the latest version tag available (or the latest tag).
- The stable image tag will be removed from DockerHub in the near future.
[setup] Removed ./setup config ssl command (deprecated since v9). SSL_TYPE=self-signed remains supported however. (dc8f49de, #2021)

`v9.1.0`

This release marks the breakpoint where the wiki was transferred to a reworked documentation

[feat] Introduce ENABLE_AMAVIS env (#1866)
[docs] Move wiki to gh-pages (#1826) - Special thanks to @polarathene 👨🏻‍💻
- You can edit the docs now directly with your code changes
- Documentation is now versioned related to docker image versions and viewable here: https://docker-mailserver.github.io/docker-mailserver/edge/

`v9.0.1`

A small update on the notification function which was made more stable as well as minor fixes.

[fix] _notify cannot fail anymore - non-zero returns lead to unintended behavior in the past when DMS_DEBUG was not set or 0
[refactor] check-for-changes.sh now uses _notify

`v9.0.0`

[feat] Support extra user_attributes in accounts configuration (#1792)
[feat] Add possibility to use a custom dkim selector (#1811)
[feat] TLS: Dual (aka hybrid) certificate support! (eg ECDSA certificate with an RSA fallback for broader compatibility) (#1801).
- This feature is presently only for SSL_TYPE=manual, all you need to do is provide your fallback certificate to the SSL_ALT_CERT_PATH and SSL_ALT_KEY_PATH ENV vars, just like your primary certificate would be setup for manual mode.
[security] TLS: You can now use ECDSA certificates! (#1802)
- Warning: ECDSA may not be supported by legacy systems (most pre-2014). You can provide an RSA certificate as a fallback.
[fix] TLS: For some docker-compose setups when restarting the docker-mailserver container, internal config state may have been persisted despite making changes that should reconfigure TLS (eg changing SSL_TYPE or replacing the certificate file) (#1801).
[refactor] Split start-mailserver.sh (#1820)
[fix] Linting now uses local path to remove the sudo dependency (#1831).

Breaking Changes

[security] TLS: TLS_LEVEL=modern has changed the server-side preference order to 128-bit before 256-bit encryption (#1802).
- NOTE: This is still very secure but may result in misleading lower scores/grades from security audit websites.
[security] TLS: TLS_LEVEL=modern removed support for AES-CBC cipher suites and follows best practices by supporting only AEAD cipher suites (#1802).
- NOTE: As TLS 1.2 is the minimum required for modern already, AEAD cipher suites should already be supported and preferred.
[security] TLS: TLS_LEVEL=intermediate has removed support for cipher suites using RSA for key exchange (only available with an RSA certificate) (#1802).
- NOTE: This only affects Dovecot which supported 5 extra cipher suites using AES-CBC and AES-GCM. Your users MUA clients should be unaffected, preferring ECDHE or DHE for key exchange.
[refactor] Complete refactoring of opendkim script (#1812).
- NOTE: Use ./setup.sh config dkim help to see the new syntax.

`v8.0.1`

This release is a hotfix for #1781.

[spam] bl.spamcop.net was removed from the list of spam lists since the domain expired and became unusable

`v8.0.0`
