man Email::MessageID () - Generate world unique message-ids.

NAME

Email::MessageID - Generate world unique message-ids.

SYNOPSIS

  use Email::MessageID;


  my $mid = Email::MessageID->new;


  print "Message-ID: $mid\x0A\x0D";

DESCRIPTION

Message-ids are optional, but highly recommended, headers that identify a message uniquely. This software generates a unique message-id.

Methods

new
  my $mid = Email::MessageID->new;

  my $new_mid = Email::MessageID->new( host => $myhost );
This class method constructs an Email::Address object containing a unique message-id. You may specify custom CWhost and CWuser parameters. By default, the CWhost is generated from CWSys::Hostname::hostname. By default, the CWuser is generated using CWTime::HiRes's CWgettimeofday and the process ID. Using these values we have the ability to ensure world uniqueness down to a specific process running on a specific host, and the exact time down to six digits of microsecond precision.
