Wietse, thanks, went through with no changes, next, I'll set 'comp level' # postfix upgrade-configuration postfix: Postfix is running with backwards-compatible default settings postfix: See http://www.postfix.org/COMPATIBILITY_README.html for details postfix: To disable backwards compatibility use "postconf compatibility_level=2" and "postfix reload" # diff main.cf main.31dec1134 # diff master.cf master.31dec1134 V
