Does it need to have a working MTA?
It relies on Test::Reporter, but I think that if you have Net::SMTP, it will use that and make a direct connection to the perl.org mail servers. If your ISP firewalls outgoing email, you'll need to set a CPAN::Reporter configuration option to point to your ISP's mail server instead.
Please give it a try and let me know if that works for you.
