Email Logging With Non-Default Port With Log4J

[Anthony Watson]

I've been trying to figure out a way that I can configure log4J to send error emails. The problem is that our admins require me to use a non-default port to connect to the SMTP server. Log4J's SMTPAppender does not seem to be able to handle any port other than 25. Does anyone have any suggestions? Is there another implementation of an SMTPAppender available that I can use that allows the port to be specified? Thanks so much. Below is the configuration I have so far:

<appender name="SMTP" class="org.apache.log4j.net.SMTPAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
<param name="Threshold" value="ERROR"/>
<param name="To" value="[email protected]"/>
<param name="From" value="[email protected]"/>
<param name="Subject" value="JBoss Sever Errors"/>
<param name="SMTPHost" value="fake.fake.com"/>
<param name="BufferSize" value="1"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ABSOLUTE},%c{1}] %m%n"/>
</layout>
</appender>

Why not write your own? You just have to subclass the SMTPAppender class, and you have the source code to work from:

1. Add an int "port" variable with getter and setter.
2. Override the activateOptions() method with a copy of the log4j code that uses the "port" variable.

I did end up writing my own and it is very simple. SMTPAppender uses JavaMail APIs behind the scenes. I just found where SMTPHost was being set in the SMTPAppender and then added getter/setter methods for smtpPort and the following:

if (smtpPort != null) {
props.put("mail.smtp.port", smtpPort);
}

Session session = Session.getInstance(props, null);
