You can try the following:

Open the file /system/plugins/ch.ivyteam.util_*.jar with a ZIP program and extract the file /lib/mvn/javax.mail-1.5.6.jar
Copy the extracted file to the directory /jre/lib/ext
Restart the engine

I changed the File in Axon Ivy\plugins\ch.ivyteam.lib.util_7.2.0.201810151000\META-INF\MANIFEST.MF The File looks ends like this: ... Created-By: Apache Maven 3.5.2 Build-Jdk: 1.8.0_151 Eclipse-BundleShape: dir Eclipse-RegisterBuddy: commons.lib

I still get the same error.

Ok thanks for the version info. My screenshot should just serves as an example on what to write into the Manifest.MF (and focuses to 7.0 users). But the procedure for 7.2.1 is different: Open the system/plugins/ch.ivyteam.lib.util_7.2.1-XYZ/META-INF/MANIFEST.MF. Add the line marked in my screenshot. Run the engine again and see whether the NoClassDefFound errors are gone.

I have Version 7.2.1. I don't have the folder util in my project explorer like in the screenshot. And when I open the file with the Plugins View, I can't edit the Manifest.mf.

Ok I see. The access from the STMPAppender to javax.mail.internet.AddressException is blocked by the default ivy bundle configuration. You could fix it with a work-around: open the plugins/ch.ivyteam.util_XYZ.jar and add an additional header to to the META-INF/Manifest.MF within it. Eclipse-RegisterBuddy: commons.lib If you can need a bulletproof solution please share the Designer version which you are using.

The SMTP Appender i want to use is a default Appender from Log4j (like the Console Appender). I don't want to build a custom Appender. Is it necessary to build a custom Appender to use the SMTP Appender?

The log appender must be made compatible with our OSGi java runtime environment.

This means that you have to enrich the JAR that supplies the appender with dependencies to our log infrastructure and register it as buddy of our commons.lib bundle.

A full blown example is accessible here: https://github.com/ivy-samples/ivy-extension-demos/tree/master/CustomLogAppender

Thanks for your answer but all Appenders are together.

May be you defined the appender at the wrong location in the log4jconfig.xml? All Appenders must be together!
