Log4j SMTPAppender Not Sending Mail

[David McWilliams]

Hi all,

I have written a small Java program to try to get log4j + SMTPAppender to log an error and send me an email when my program throws an exception. The exception is being correctly logged but no mail is being sent.

I have tested my program to see if it sends mail and it does - just not via log4j. I am using a log4j.properties file to configure the logging.

Have any of you any ideas why my email is not being sent when I throw an exception? Here is my log4j.properties file:

log4j.rootLogger=DEBUG, sendMail
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%5p] %d{mm:ss} (%F:%M:%L)%n%m%n%n

log4j.appender.sendMail=org.apache.log4j.net.SMTPAppender
log4j.appender.sendMail.Threshold=WARN
log4j.appender.sendMail.To=[e-mail]
log4j.appender.sendMail.From=[e-mail]
log4j.appender.sendMail.SMTPHost=mailhost.x.com
log4j.appender.sendMail.Subject=Log4J Message
log4j.appender.sendMail.layout=org.apache.log4j.PatternLayout
log4j.appender.sendMail.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.sendMail.BufferSize=1
log4j.appender.sendMail.SMTPDebug=true

It's working now. In my code, I was calling

log4j.rootLogger=DEBUG
logger.warn("error");

I changed it to:

log4j.rootLogger=DEBUG
logger.error("error");
