That "same code" is commented out in the Postfix 2.11 "post-install" script. It was only present in 2.10 and some early 2.11 snapshots. Introduced: postfix-2.10-20121031 Improved to handle empty explicit values: postfix-2.10-20121007 Commented out: postfix-2.11-20130613 There is no version of Postfix that added the smtpd_relay_restrictions safety net when an explicit non-empty value was present in main.cf. The server in question had the "safety-net" value added by something other than Postfix "upgrade-configuration". And certainly not by Postfix 2.11 where the code to do so is NOT present. -- Viktor.
