RE: [SAtalk] [RD] Creating rule for time accepted

[Ernest W. Lessenger]

I wrote a quick eval function that work as a proof-of-concept only. It
doesn't look at the headers at all... it uses the current system time and
*assumes* that the email is being scanned within a few minutes of being
received by the local server. I am aware that this is a weak assumption
in many (most?) cases, but this code has the advantage of being
absolutely immune to forged Date: or Received: headers.
** Append to EvalTests.pm
sub received_between {
  my ($self, $min, $max) = @_;
  local ($_);
  my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) =
localtime();
  my $timeString = $hour.$min;
  if ($min < $max) {
    return 1 if (($timeString > $min) &&
($timeString < $max));
  }
  else {
    return 1 if (($timeString > $min) || ($timeString
< $max));
  }
  return 0;
}
Append to 20_head_tests.cf
header RECVD_OUTSIDE_BUS_HOURS 
eval:received_between(1900,0800)
describe RECVD_OUTSIDE_BUS_HOURS The last Received: date was outside of
business hours
A business (eg) might want to give this rule a small positive value,
while an ISP (eg) might want to give it a small negative value.

The Camel Book? Seriously, you should learn Perl if you want to write an

eval function; it's not as simple as a one-line rule. If you do
understand 
Perl, then looking at a few of the other functions in 
Mail::SpamAssassin::EvalTest.pm should make it clear how they
work.
