Comment # 1 on bug 1057940 from Per Jessen

Looking at /usr/lib/postfix in Leap423, it does have some unusual stuff:

l /usr/lib/postfix/

drwxr-xr-x  2 root root      1 May 18 02:29 dynamicmaps.cf.d/

-rwxr-xr-x  1 root root 256768 May 18 02:29 libpostfix-util.so*

Those libraries belong in /usr/lib64, where they used to be.

Some sort of packaging issue?
