You could also try something like this:

use Net::SMTP;

my $message="This is a test of the Emergency Email Network.";
my $address=q!address1@someplace.com; address2@anotherplace.com; addre
+ss3@anywhere.com!;
my @address=split(/; /,$address);
my $sendmail=Net::SMTP->new('mailserver') or die $!;
$sendmail->mail('mailfromme@myplace.com');

foreach (<@address>) {$sendmail->to($_);}

$sendmail->data();
$sendmail->datasend("To: $address\n");
$sendmail->datasend("Subject: My Subject\n");
$sendmail->datasend("\n");
$sendmail->datasend($message);
$sendmail->dataend;

Granted I'm probably doing extra work in the snippet, but it serves its purpose and does what I want it to do.
