Bingo. Your Postfix software is not properly installed. My Postfix 3.6.4 "master" executable does not have a "var_compat_level" symbol: # objdump -T /usr/libexec/postfix/master | grep compat_level 0000000000000000 DF *UND* 0000000000000000 Base compat_level_from_string 0000000000000000 DO *UND* 0000000000000000 Base compat_level and correspondingly in libpostfix-global we see: # objdump -T /usr/lib64/postfix/libpostfix-global.so | grep compat_level 0000000000034be0 g DF .text 000000000000008d Base compat_level_relop_register 0000000000034760 g DF .text 0000000000000150 Base compat_level_from_string 00000000000349f0 g DF .text 00000000000000c5 Base compat_level_from_numbers 000000000004e7c0 g DO .bss 0000000000000008 Base compat_level 0000000000034ac0 g DF .text 0000000000000120 Base compat_level_to_string Your "master" executable appears to be from an older Postfix version. -- Viktor.
