An email address containing an ampersand (&) character was not allowed when configuring an alarm in Log Insight. Ampersand is among the valid special characters for the "local" portion of an email address, per RFC5322. In fact, MOST of the special characters allowed in the local-portion by RFC5322 are not considered valid in the Log Insight alarms. Please correct the defect in Log Insight that is preventing use of a fully-valid email address that uses special characters in its local portion.
