Hummm. Did you pass first argument FROM_DOMAIN to start() ?
Some SMTP servers reject mail if FROM_DOMAIN is not correct.
"Correct domain" is, for example, the domain which the server
cannot lookup it from DNS, like dial-up host.

Net::SMTP tries to use gethostname(2) when first argument is
omitted, but it may not return "correct" host name.
