Hello Greg, Add the following line to your logback.xml config file to see the error message output when SMTPAppender sends out a message. <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener" /> For more info on OnConsoleStatusListener see [1]. By the way, you should not declare logback-access as a dependency if you are not using logback-access.

Hi,

I'm trying to setup logback for a fairly simple appender configuration..

DEBUG, INFO, WARN: System.out Console Appender, File Appender ERROR: System.err Console Appender, File Appender, SMTPAppender configured for GMail.

Following instructions to setup GMail appender, I have the following:

Appender config:

<!-- Email appender --> <appender name="MailAppender" class="ch.qos.logback.classic.net.SMTPAppender"> <smtpHost>smtp.gmail.com <http://smtp.gmail.com></smtpHost> <smtpPort>465</smtpPort> <ssl>true</ssl> <username>MyUsername</username> <password>MyPassword</password>

<to>greg@klout.com <mailto:greg@klout.com></to> <!--<to>ANOTHER_EMAIL_DESTINATION</to> <!– additional destinations are possible –>--> <from>noreply@gmail.com <mailto:noreply@gmail.com></from> <subject>LOGGED ERROR: %logger{20} - %m</subject> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%date %-5level %logger{35} - %message%n%xEx{35}</pattern> </layout> </appender>

Appender inclusion:

<root level="ERROR"> <appender-ref ref="StdErrAppender" /> <appender-ref ref="FileAppender" /> <appender-ref ref="MailAppender" /> </root>

All appropriate maven dependencies:

logger jars

<slf4j.version>1.6.4</slf4j.version>

<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-access</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>1.0.0</version> </dependency>

java mail <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.4</version> </dependency>

All the other appenders work just fine as configured. I see that the SMTPAppender is being loaded w/o error (at least nothing I see reported) .. yet on ERROR nothing gets sent. Username & password are all correct. I've confirmed with our operations that we don't have any special spam filters set up.

Thoughts on what could be wrong / what I need to check?

Thanks -greg
