If you want to receive an email every time an error occurs,
i recommend to use the smtp appender of log4j:
<appender name="mail" class="org.apache.log4j.net.SMTPAppender">
<param name="SMTPHost" value="smtp.yourhost.com" />
<param name="From" value="[EMAIL PROTECTED]" />
<param name="To" value="[EMAIL PROTECTED]" />
<param name="Subject" value="[Your App] Exception" />
<param name="BufferSize" value="0" />
<param name="threshold" value="WARN" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ABSOLUTE} %5p %c{1}:%L
- %m%n" />
</layout>
</appender>
Bye,
