in order to receive logs and alerts by email, you must provide your email information in the e-mail tab:

1?mail server
specifies the name of your outgoing (smtp) mail server. you can enter either the server name (such as mail.myisp.com) or its ip address. if you leave this box blank, log and alert messages are not sent via e-mail.
2?e-mail to
specifies the e-mail address to which logs and alerts are sent. this e-mail address will be used as the from address. if you leave this box blank, the log is not sent via e-mail to any address.
you can specify that logs are automatically sent to the specified e-mail address with these options:
1?send immediate alert upon attempted access to a blocked site
check this box if you would like immediate notification of inappropriate access attempts.
2?log schedule
specifies how often to send the logs: hourly, daily, weekly, or when full.
3?day for sending log
specifies which day of the week to send the log. relevant when the log is sent weekly or daily.
4?time for sending log
specifies the time of day to send the log. relevant when the log is sent daily.
5?time zone
specify your local time zone and click apply. this setting will be used for the blocking schedule and also for time-stamping log entries.
if the weekly, daily or hourly option is selected and the log fills up before the specified period, the log is automatically e-mailed to the specified e-mail address.
after the log is sent, the log is cleared from the router’s memory. if the router cannot e-mail the log file, the log buffer may fill up. in this case, the router overwrites the log and discards its contents.
