logging email

This command enables email alerting and sets the lowest severity level for which log messages are emailed. If you specify a severity level, log messages at or above this severity level, but below the urgent severity level, are emailed in a non-urgent manner by collecting them together until the log time expires. You can specify the severitylevel value as either an integer from 0 to 7 or symbolically through one of the following keywords: emergency(0), alert(1), critical(2), error(3), warning(4), notice(5), info (6), or debug(7).
