The bash script converts the S25R whitelist in the postfix format into the whitelist in the milter-greylist format

Introduction

When you make use of the S25R anti-spam system for the sendmail and the milter-greylist,
taking advantage of the published S25R whitelist, an email from the sender matching the S25R rules
can be received without any delay by greylisting function.

The format of the S25R whitelist published at the S25R home page is the format for the postfix.
This bash script converts it into the format for the milter-greylist.

Format conversion

Published S25R whitelist for the postfix		Converted S25R whitelist for the milter-greylist
/\.example\.jp$/	Having alphabets	racl whitelist domain /\.example\.jp$/ sm_macro "whitelist-linenumber" "_" /\.example\.jp \[/ racl whitelist sm_macro "whitelist-linenumber" or ( *1 ) racl whitelist domain /\.example\.jp$/
/^192\.0\.2\.1$/	A single IP address	racl whitelist addr 192.0.2.1
/^172\.16\.9[6-9]\.[0-9]+$/	The 3rd. octet and the 4th. octet are predefined in the script ( *2 )	racl whitelist addr 172.16.96.0/22
/^192\.0\.2\.1(6[1-9]\|7[0-4])$/	The 4th. octet is predefined in the script ( *3 )	racl whitelist addr 192.0.2.160/28
/^192\.0\.2\.22(8\|9)$/	The ( ) regex of the 4th. octet expresses the CIDR /31 subnet	racl whitelist addr 192.0.2.228/31
/^192\.0\.2\.23[4-5]$/	The [ ] regex of the 4th. octet expresses the CIDR /31 subnet	racl whitelist addr 192.0.2.234/31
/^192\.0\.2\.1(3[2-4]\|40)$/	The ( ) and/or [ ] regex expresses plural IP addresses ( *4 )	list "whitelist-linenumber" addr { 192.0.2.132 192.0.2.133 192.0.2.134 192.0.2.140 } racl whitelist list "whitelist-linenumber"
Complex, etc	Can not expand the regex ( *5 )	# white-list.txt : Line=number, Reason

*1 The command-line option -p specifies converted verbs.
*2 The REGEX_OCTET3_4 array variable in the script.
*3 The REGEX_OCTET4 array variable in the script.
*4 The MAX_EXPAND_REGEX variable in the script limits the number of IP address to be expanded from the regex.
*5 In the published S25R on Jul. 10, 2013, 3 regex's can not be converted.

Usage

s25r-whiteconv.sh [-b] [-p] inputfile outputfile

-b: Regex of domain that begins with \. is converted into non-regular expression.
This option is used in conjunction with the 'domainexact' keyword of the milter-greylist configuration file.
-p: Even if the IP address is successfully looked up, forged IP address is considered to be unresolved IP address.
The regex of the domain is converted into only 'racl whitelist domain'.
inputfile: The downloaded S25R whitelist for the postfix from S25R whitelist download page
outputfile: The converted whitelist for the milter-greylist
