Hi The 's' modifier is not working in a body_checks regex entry within postfix 2.11.1, but it does work in an online regex checker eg regex101:
/((?=.*website)|(?=.*mywebsite\.com\.au))((?=.*purchase)|(?=.*great)).*/s REJECT eg a test file is REJECTED if it has contents: website great but in my postfix it is NOT rejected if the two words in the test file are separated by a carriage return: website great (am testing via: postmap -q - pcre:/etc/postfix/body_checks < /etc/postfix/testfile Thanks Michael
