SYNOPSIS
use Email::MessageID;
# bare ID

DESCRIPTION
The Email::MessageID distribution provides an algorithm to create unique strings (ID) for a given host / user combination.
EXPORTED SUBROUTINES
message-id
The message-id subroutine returns a unique string for a given host and user (specified as named arguments).
The default value for the :host named argument is Kernel.hostname.
The default value for the :user named argument is a random string created from several different random sources.
The default value for the :header named argument is False. If specified with a trueish value, will generate a string that can be used verbatim in an email header.
