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.
