The DBMAIL package replaces the normal UNIX mailing system. All email and user data is stored in a database. You can create an unlimited number of email accounts, which can be checked using the POP3 or IMAP protocol. Users can maintain their own set of email addresses. It is more scalable, more secure, and faster than traditional mail systems. DBMAIL has storage drivers for PostgreSQL and MySQL, and it has authentication drivers for PostgreSQL, MySQL, and LDAP.

Release Notes: Using bind=* will crash on accept. Slow IMAP results and high CPU usage when message_idnr is very big were fixed. The IMAP daemon no longer uses 100% CPU if a file is attached to mail a message. The IMAP daemon now sends ')\r\n' after a message. IMAP-ID capability was added to the IMAP daemon.
Release Notes: Text with unknown encoding is better converted to UTF-8, and character sets are correctly handled for IMAP SEARCH. The IMAP IDLE command is now allowed at any time, improving Outlook compatibility. A BSD build error was corrected.
Release Notes: This release features greatly improved handling of UTF8 email, has many fixes for IMAP protocol errors, and resolves a number of serious memory leaks. A new feature was added to dbmail-export to allow fine-grained message selection and post-export deletion.
Release Notes: This release resolves several regressions and long-standing but subtle IMAP compliance issues, and introduces ~ expansion for SQLite database paths, suddenly allowing great horizontal scalability (at the expense of any #Users and #Public namespaces). dbmail-export sometimes produced upside-down messages (body first, then headers), the Recent flag was not cleared correctly, IMAP SEARCH LARGER and SEARCH SMALLER did not work, proper handling and logging of a full /tmp filesystem, and higher level logging of messages returned due to quota limits have all been fixed.
Release Notes: The major bugfixes in this release relate to PostgreSQL query errors in certain database encodings, causing some messages to remain in the MTA queue until they are returned to sender. All DBMail/PostgreSQL users should upgrade. Two user-facing changes are that dbmail-users now has a -n switch for dry-run mode, and dbmail.conf now has two new entries: encoding and default_msg_encoding. Empty convenience libraries are no longer installed for unbuilt modules. A wider tolerance is allowed for some unusual email addresses. Several small protocol glitches in IMAP and POP3 daemons are fixed.
