Obviously you failed to connect to the server in those bad cases.

It is always a better practice to check return code on eah step. You cannot expect that the connection works all the time, but you should expect your code to handle exceptional situations.

$smtp = Net::SMTP->new('mailhost', Timeout => 60);
