Postfix::Parse::Mailq - parse the output of the postfix mailq command
version 1.005
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";
my $entries = Postfix::Parse::Mailq->read_string($string, \%arg);
This methods read the output of postfix's 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 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!)
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.
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.
