Release Notes: This release enhances STARTTLS support and fixes some configuration inconsistencies. For example, a new option for smtps has been added: CAlist_file. If specified, it is used instead of CAcert_file for SSL_CTX_set_client_CA_list(3), which sets the list of CAs sent to the client when requesting a client certificate.
Release Notes: This release relaxes the requirement for successful DNS lookups and adds several more STARTTLS-related features.
Release Notes: This release works on Darwin 12 and adds more TLS enhancements.
Release Notes: This release adds an option for tls_requirements to specify hostname patterns which are matched against subjectAltName or the CN of a server cert, as well as another a way to override a DNSBL rejection. Moreover, this version contains significantly more IPv6-related code, but it isn't production-ready, as it doesn't handle all error case yet. However, if you have an IPv6 test environment, please give it a try (compiled with -DMTA_NETINET6).
Release Notes: MeTA1 1.0.Alpha15.0 is available for testing. It includes a new version of statethreads. This version also fixes some autoconf problems and the handling of 64 bit time_t values. Note: If your OS has sizeof(time_t) == 8 (e.g., most 64-bit OS), then the DEFEDB (on-disk) format changes, so if you upgrade to Alpha15, make sure the queue is empty before you switch over.
Release Notes: This release enables basic DH support for STARTTLS in the SMTP server and modifies the behavior of the scheduler if a limit for outgoing connections is reached.
