We've used this package to make sure our email environment is delivering messages in a timely fashion. It's a great tool. However, it hasn't been updated in some time. check_smtp_send depends on Net::SMTP::TLS which is no longer maintained and breaks with new IO::Socket::SSL. That's when you'll see: invalid SSL_version specified The fix is to change check_smtp_send to use Net::SMTP which now directly supports STARTTLS.
