Email::MessageID(3) User Contributed Perl Documentation Email::MessageID(3)NAMEEmail::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.
create_host
my $domain_part = Email::MessageID->create_host;
This method returns the domain part of the message-id.
create_user
my $local_part = Email::MessageID->create_user;
This method returns a unique local part for the message-id. It
includes some random data and some predictable data.
in_brackets
The Message-Id header must start and end with angle brackets. This is
a common mistake:
header => [
...
'Message-Id' => Email::MessageID->new->as_string,
],
Instead, use "in_brackets" to get the string inside angle brackets.
