This feature can be enabled if you want the security appliance to notify network administrators immediately when special log messages are generated. When a special event occurs, the security appliance "contacts" the mail server specified in the local configuration and sends an email to the recipient based on the pre-configured email account information. When mail logging is enabled and the severity of Syslog log messages sent by mail is specified as notification or debugging, it may cause the mail server or CiscoASA to crash. 5.5.
