Right, this was missing a space after the "Received:" header name. > Try /^Received:\s+from\s+foo\.domain\b/ ... So the above is better, but "\b" is not ideal, because a literal "." is also a word-boundary. Thus: Try (switching to reserved the .example TLD): /^Received:\s+from\s+domain\.example\s+/ ... because there will always be more text after the domain, e.g. the final newline if nothing else. -- Viktor.
