Here is a new version of Postfix, just released and I’ve got it tested on Snow Leopard and Leopard on my test machines. It solves some small bugs as listed below:

  • Fixed a “signal 11″ bug with Postfix SMTP server debug logging at smtpd_tls_loglevel ≥ 3.
  • The Postfix SMTP and QMQP servers no longer look up IPv6 address information while looking up the FCRDNS (forward-confirmed reverse DNS) hostname for an IPv4 remote client (and vice versa).
  • The postscreen(8) daemon no longer logs a “connection reset by peer” warning when a remote SMTP client hangs up prematurely.
  • Removed spurious configuration parameters from “postconf” output, by deleting the #ifdef MIGRATION_WARNING transitional code from postscreen(8).
  • Assorted minor documentation fixes.

Note:
Some people have reported problems with updating from an older version that the TLS is no longer working. If you upgrade please add this line to your main.cf configuration file:

smtpd_tls_exclude_ciphers = SSLv2, aNULL, ADH, eNULL

and restart postfix. Everything should work as expected.

As usual you can read the instructions on how to upgrade Postfix at Upgrading Postfix.
