You may want to check this again: DNS lookups results will sometimes change over time. There are no changes in postscreen source code. There are no changes in files that handle configuration settings. The changes in the two global library files are not in code that postscreen depends on. The changes in the tls library do not affect postscreen's DNSBL code. However if Postfix 3.7.2 was built with a different compiler then some things may change even if the code did not. These are the files that are changed with Postfix-3.7.3: $ zcat postfix-2.3-patch-03.gz | grep '^d' diff -ur --new-file /var/tmp/postfix-3.7.2/src/global/mail_version.h ./src/global/mail_version.h diff -ur --new-file /var/tmp/postfix-3.7.2/HISTORY ./HISTORY diff -ur --new-file /var/tmp/postfix-3.7.2/RELEASE_NOTES ./RELEASE_NOTES diff -ur --new-file /var/tmp/postfix-3.7.2/src/cleanup/cleanup_milter.c ./src/cleanup/cleanup_milter.c diff -ur --new-file /var/tmp/postfix-3.7.2/src/global/map_search.c ./src/global/map_search.c diff -ur --new-file /var/tmp/postfix-3.7.2/src/global/verify.c ./src/global/verify.c diff -ur --new-file /var/tmp/postfix-3.7.2/src/oqmgr/qmgr_message.c ./src/oqmgr/qmgr_message.c diff -ur --new-file /var/tmp/postfix-3.7.2/src/qmgr/qmgr_message.c ./src/qmgr/qmgr_message.c diff -ur --new-file /var/tmp/postfix-3.7.2/src/tls/tls_server.c ./src/tls/tls_server.c
