        <param name="BufferSize" value="512" />
        <param name="SMTPHost" value="smtp.gmail.com" />
        <param name="From" value="YYY@yahoo.fr" />
        <param name="To" value="XXX@gmail.com"/>
 
        <param name="Subject" value="[SMTPAppender] Application message" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern"
              value="[%d{ISO8601}]%n%n%-5p%n%n%c%n%n%m%n%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="ERROR"/>
            <param name="LevelMax" value="FATAL"/>
        </filter>
