Module Version: 1.31   Source   Latest Release: Email-MessageID-1.405

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 host and user parameters.

By default, the host is generated from Sys::Hostname::hostname.

By default, the user is generated using Time::HiRes's gettimeofday 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.

SEE ALSO ^

Email::Address, Time::HiRes, Sys::Hostname, perl.
