An update that has two fixes can now be installed.

Description:

This update for postfix fixes the following issues:

  • Postfix version update to 3.3.1 (bsc#1094965)
  • Postfix did not support running as a PID=1 process, which complicated Postfix deployment in containers. The "postfix start-fg" command will now run the Postfix master daemon as a PID=1 process if possible. Thanks for inputs from Andreas Schulze, Eray Aslan, and Viktor Dukhovni.
  • Segfault in the postconf(1) command after it could not open a Postfix database configuration file due to a file permission error (dereferencing a null pointer). Reported by Andreas Hasenack, fixed by Viktor Dukhovni.
  • The luser_relay feature became a black hole, when the luser_relay parameter was set to a non-existent local address (i.e. mail disappeared silently). Reported by J?rgen Thomsen.
  • Missing error propagation in the tlsproxy(8) daemon could result in a segfault after TLS handshake error (dereferencing a 0xffff...ffff pointer). This daemon handles the TLS protocol when a non-whitelisted client sends a STARTTLS command to postscreen(8).
