email::received
Email::Received(3pm) User Contributed Perl Documentation Email::Received(3pm)
NAME
Email::Received - Parse an email Received: header
SYNOPSIS
use Email::Received;
for ($mail->header("Received")) {
my $data = parse_received($_);
return "SPAM" if rbl_lookup($data->{ip});
}
DESCRIPTION
This module is a Perl Email Project rewrite of SpamAssassin's email header parser. We did this so that the great work they did in analysing
pretty much every possible Received header format could be used in applications other than SpamAssassin itself.
The module provides one function, "parse_received", which takes a single Received line. It then produces either nothing, if the line is
unparsable, a hash reference like this:
{ reason => "gateway noise" }
if the line should be ignored for some good reason, and one like this:
{ ip => '64.12.136.4', id => '875522', by => 'xxx.com',
helo => 'imo-m01.mx.aol.com' }
if it parsed the message. Possible keys are:
ip rdns helo ident envfrom auth by id
RULE FORMAT
Where SpamAssassin used a big static subroutine full of regular expressions to parse the data, we build up a big subroutine full of regular
expressions dynamically from a set of rules. The rules are stored at the bottom of this module. The basic format for a rule looks like
this:
((var=~)?/REGEXP/)? [ACTION; ]+
The "ACTION" is either "SET variable = $value", "IGNORE "reason"?", "UNPARSABLE" or "DONE".
One control structure is provided, which is basically an "if" statement:
GIVEN (NOT)? /REGEXP/ {
ACTION+
}
EXPORT
parse_received
SEE ALSO
Mail::SpamAssassin::Message::Metadata::Received, from which the rules and some of the IP address matching constants were blatantly stolen.
Thanks, guys, for doing such a comprehensive job!
