Fixed a few warning messages I ran into today when SMTP had died. We already output nice SMTP error messages, so no need to have the PHP code display its own errors.

Also, the property dlv_server_msg was only being set in the errorCheck function, which was never ran if the socket connection failed, so we would get an undefined error.
