You are right. But to be honest this should be enough (just an example): 001) if /^Received|X\-((Origin(ating)?|Client|MDRemote|Sender)\-?IP|(Client|Remote_)Addr|PHP\-Script):/ 002) /\b(127\.0.\d+\.\d+)\b/ REJECT aviso.ci junk 2 003) endif * Rule 001 will match a specific header. * Rule 002 will match 127.0.xxx.xxx * 127.0.xxx.xxx could be anchored with ^ but the rule/if-condition in 001 is already taking care of that 127.0.xxx.xxx is not part of the header name. So you can shorten the regexp to just "/\b(<ip you check/rule>)/b REJECT blah-blah-blah" > Thanks, > No problem. // Steve -- Sicherer, schneller und einfacher.
