Hi,

I upgraded to logback 1.0.0 in a web application (tomcat 5, JDK 1.5), and the ERROR email are not sent anymore from the SMTPAppender.
When I rollback my logback-core and logback-classic JARs to version 0.9.30, it's working again.

I have a simple config:

    <appender name="courriel" class="ch.qos.logback.classic.net.SMTPAppender">
        <smtpHost>smtp.xxx.xx.xx</smtpHost>
        <to>xxx@xxx.xx.xx</to>
        <from>no-reply.ti@xxx.xx.xx</from>
        <subject>Test</subject>
        <cyclicBufferTracker class="ch.qos.logback.core.spi.CyclicBufferTrackerImpl">
            <bufferSize>25</bufferSize>
        </cyclicBufferTracker>
        <layout class="ch.qos.logback.classic.html.HTMLLayout">
            <pattern>%date%level%thread%logger%line%message</pattern>
        </layout>
    </appender>

I am using logback 1.0.0 with no problem in an other project (with JDK 1.6).
Is there any known compatibility problem between logback 1.0.0 and JDK 1.5?

Thanks,
Louis-Félix
