Postfix, a mail server that started life at IBM research as an alternative to the widely-used Sendmail program, is now at version 2.9.6.Highlights of Postfix 2.9.6:
• Thanks to OpenSSL documentation, the Postfix 2.9.0..2.9.5 SMTP client and server used an incorrect procedure to compute TLS certificate PUBLIC-KEY fingerprints (these may be used in the check_ccert_access and in smtp_tls_policy_maps features);
• The postconf(1) master.cf parser didn't support "clusters" of daemon command-line option letters;
• The local(8) delivery agent dereferenced a null pointer while delivering to null command (for example, "|" in a .forward file). Reported by Gilles Chehade;
• A memory leak fix for tls_misc.c was documented, but not included;
• Support for certificate PUBLIC-KEY finger prints was introduced with Postfix 2.9.
