maddy 0.3.0 **Stability:** This version is believed to be stable enough for use in use non-critical deployments. == Breaking changes * Minimal supported Go version is increased to Go 1.14 maddy keeps tracking latest Go version to benefit from language and library improvements. build.sh script will automatically download a newer toolchain version if system installed version is too old. * Fully separate authentication from IMAP access Now there is no uniform database that is used both for IMAP index and authenticaiton. This allows completely independent implementation and leveraging of maddy modular framework for more flexible authentication documentation. This is a breaking change that also affects how password hashes are calculated and requires destructive changes to databases created in 0.2 order to use with 0.3. A migration utility is created to assist with that. See Upgrading page in documentation for detailed instructions. == New features * Preliminary milter client implementation This release introduces limited implementation of milter client protocol. Due to a number of differences between how maddy handles internal filtering and protocol model "milters" currently cannot make most modifications to the message content and is limited to prepending headers and quarantining or rejecting message. * source_in, destination_in directives for message pipeline Directives `source_in` and `destination_in` allow matching of message senders or recipients against lists sources from table modules (files, SQL queries, etc). See maddy-smtp(5) for details. * Dovecot authentication client support maddy now implements client side of Dovecot authentication protocol allowing it to be used with Dovecot as an IMAP server instead of builtin server. * Dovecot-compatible sasld endpoint Additional, maddy also implements Dovecot-compatible sasld endpoint that allows it to be used as a source for authentication data for other servers that support Dovecot authentication protocol (e.g. SMTP servers like Postfix). * lmtp_downstream delivery target maddy now has full implementation of LMTP client allowing messages to be forwarded to other software that speaks LMTP protocol. * endpoint/smtp: Allow to choose the IP to use for outbound smtp. * modify/dkim: Allow to sign emails from subdomains using a top domain key == Improvements * cmd/maddyctl: Create a set of typical mailboxes on IMAP account creation * endpoint/smtp: Send 535 on permanent authentication failure * target: Make Received generation more robust in case of missing data * config: Support scheme:IP:PORT syntax for endpoint declaration == Bug fixes * storage/imapsql: Fix SPECIAL-USE support being accidentally disabled * Fix and improve -v flag description * endpoint/smtp: Fix missing server hostname in Received header * target/remote: Do not fail delivery with null return path == Documentation improvements * Fix a number of links in documentation * Add page about IMAP-only configuration * Mention disabled HZGB2312 support * Add smtp-only.md page * Add imap-only.md page * Add FAQ page * Add upgrading instructions page
