Release Notes: Various changes were made.
Release Notes: This release fixes a potential smtps restart if smar does not answer in time. A pmilter is used, and access checks are delayed.
Release Notes: This release included a fix to handle an error condition if FFR_CERT_PINNING is used.
Release Notes: This release fixes IPv6-related deficiencies and adds new features for TLS (Digest) and mcp (failure_max).
Release Notes: This release adds features to deal with TLS interoperability problems.
Release Notes: This version enhances handling of failures of processes that are under control of mcp and adds cert pinning as an experimental feature.
Release Notes: This release fixed a stack alignment problem for *BSD based OSs in statethreads, which caused crashes when compiled against a recent OpenSSL version which uses asm code for SHA functions. It also introduced an incompatible change for the lookup algorithm in maps for IP addresses, fixed a "dot-stuffing" bug in contrib/femail.c, and added some more TLS and IPv6 related enhancements.
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).
