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
