Qmail::Deliverable::Client(3)

NAME
Qmail::Deliverable::Client - Client for qmail-deliverabled

SYNOPSIS
    use Qmail::Deliverable::Client qw(deliverable);

    $Qmail::Deliverable::Client::SERVER = "127.0.0.1:8998";

    if (deliverable "foo@example.com") { ... }

DESCRIPTION
Qmail::Deliverable comes with a daemon program called qmail-deliverabled. This module is a front end to it.

This module requires LWP (libwww-perl), available from CPAN.

  Error reporting
The error message for communication failure is reported via a warning, but also available via $Qmail::Deliverable::Client::ERROR.

  Configuration

$Qmail::Deliverable::Client::SERVER
    IP adress and port of the qmail-deliverabled server, joined by a colon. Defaults to "127.0.0.1:8998", just like the daemon.

    This variable can also be assigned a code reference, in which case it is called in scalar context for each remote call, using the returned value.

    If the value is undef, then a connection failure is faked, but without the warning.

  Functions
All documented functions are exportable, and a tag :all is available for convenience.

Unless documented differently, these functions follow the interfaces described in Qmail::Deliverable.

qmail_local $address
    As Qmail::Deliverable::qmail_local. Warns and returns "" on communication failure.

deliverable $address
deliverable $local
    As Qmail::Deliverable::deliverable. Warns and returns 0x2f on communication failure.

PERFORMANCE
The server on which I benchmarked this, the client+daemon combination (on localhost) reached 300 deliverability checks per second for assigned/virtual users. Real users are slower: around 150 checks per second.
