Docker Mailserver, a comprehensive solution for setting up a mail server including spam and virus protection with Docker containers, has been released in version 15. One of the new features is that the setup command line tool requires password confirmation for some functions. There are also some changes to authentication via Simple Authentication and Security Layer (SASL) that are incompatible with the previous version: only ldap and rimap are now supported. Support for PAM, Shadow and MySQL has ended.

In addition, getmail6 has been refactored. The mail retriever, which collects mails from POP3 and IMAP4 servers, now allows overwriting the default configuration in the config volume of the mail server. Instead of individual logs for each configuration, the tool logs possible errors in a common log file by default. The developers have also fixed a bug from the previous version, which also changed the directory structure for configuration files. When updating to the new version, users must migrate the files to the new directories themselves.

In Docker Mailserver 15, the developers have also removed the path check for the Rspamd configuration file, which is no longer required. They have also updated the included third-party software. Dovecot is now available in version 2.4, the associated FTS-Xapian module in 1.9. Also included are Fail2Ban 1.1, jaq 2.1 and Rspamd 3.11. All new features are listed in the changelog.
