Hi, via some recent testing. I saw that RCVD_NUMERIC_HELO was being fired when
the helo detected by SA was of the form a.b.c.d.in-adddr.arpa (where a.b.c.d)
was an ip address in reverse octect form
I wrote the following test case which uses the constant IPV4_ADDRESS from the
SA source to show this behaviour.
#!/usr/bin/perl
use strict;
use warnings;
use Test::More tests => 1;
use constant IPV4_ADDRESS => qr/\b
(?:1\d\d|2[0-4]\d|25[0-5]|\d\d|\d)\.
(?:1\d\d|2[0-4]\d|25[0-5]|\d\d|\d)\.
(?:1\d\d|2[0-4]\d|25[0-5]|\d\d|\d)\.
(?:1\d\d|2[0-4]\d|25[0-5]|\d\d|\d)
\b/ox;
sub check_ipv4 {
my ($rcvd) = @_ ;
my $IP_ADDRESS = IPV4_ADDRESS;
if ($rcvd =~ /helo=($IP_ADDRESS)\b/i) {
return 1;
}
return 0;
}
my $helostring = "helo=242.8.168.192.in-addr.arpa";
ok(check_ipv4($helostring) == 1);
