=head1 NAME
Postfix::Parse::Mailq - parse the output of the postfix mailq command
=head1 VERSION
version 1.001
=head1 SYNOPSIS
use Postfix::Parse::Mailq;
my $mailq_output = `mailq`;
my $entries = Postfix::Parse::Mailq->read_string($mailq_output);
my $bytes = 0;
for my $entry (@$entries) {
next unless grep { /\@aol.com$/ } @{ $entry->{remaining_rcpts} };
$bytes += $entry->{size};
}
print "$bytes bytes remain to send to AOL destinations\n";
=head1 WARNING
This code is really rough and the interface will change. Entries will be
objects. There will be some more methods. Still, the basics are likely to
keep working, or keep pretty close to what you see here now.
=head1 METHODS
=head2 read_file
=head2 read_handle
=head2 read_string
my $entries = Postfix::Parse::Mailq->read_string($string, \%arg);
This methods read the output of postfix's F<mailq> from a file (by name), a
filehandle, or a string, respectively. They return an arrayref of hashrefs,
each hashref representing one entry in the queue as reported by F<mailq>.
Valid arguments are:
spool - a hashref of { queue_id -> spool_name } pairs
if given, this will be used to attempt to indicate in which
spool messages currently are; it is not entirely reliable (race!)
=head2 parse_block
my $entry = Mailq->parse_block(\@lines);
Given all the lines in a single entry's block of lines in mailq output, this
returns data about the entry.
