Just a quick tutorial. As PCRE is much quicker than using regular line matching I use the following when checking against REVDNS within filters:
Regular Filter line: --------------------------- REVDNS -5 ENDSWITH .bigfootinteractive.com REVDNS -5 ENDSWITH .bluehornet.com REVDNS -5 ENDSWITH .constantcontact.com PCRE Filter line: --------------------------- REVDNS -5 PCRE (?i:\.(bigfootinteractive|bluehornet|constantcontact)\.com$) 1. The PCRE expression needs to be in parenthesis ( ) 2. ?i: indicates case in-sensitive 3. As . is a special character meaning any character we use the \ to indicate that it should just be a . 4. The | represents or 5.The $ is also a special character which used here indicates the end of a string The above PCRE will match any of the 3 from the regular filter.
