As far as I can tell, that IP address is invalid. It is listed by IANA as "unallocated". If you are using this IP block internally, you will need to edit the function to allow it. Try this modification to the function: return 1 if ($check =~ /^ (?:[0257]|(?!127.0.0.)127|22[3-9]|2[3-9]\d|[12]\d{3,}|[3-9]\d\d+)\.\d+\.\d+\ .\d+ $/x); I removed the '1' in the first character class in the regex. This will prevent the regex from matching on 1.x.x.x addresses. Keep in mind that you will most likely have to modify this function each time you update SpamAssassin. -- Bowie
