Bad variables from copy/paste?

[jefflage]

starting on line 59 of node_mailer.js, it seems that the callbacks for handling close and empty have been copy/pasted from the addClient method and those two methods use different names for the hostClients/hostpool variables so the callbacks fail in the send method.

Same error here:
"
ReferenceError: host is not defined
at SMTPClient. (node_mailer.js:63:33)
