Thank you. But this isn't the core problem

I add the option -Djavax.activation.debug=true and this is printed out.

As I told, sending from scratch is ok. If I use SMTPAppender it might be a
classloading problem of SMTPAppender, or at least I assume it. Have to look
at the source
(ch.qos.logback.core.net.SMTPAppenderBase.sendBuffer(SMTPAppenderBase.java:352))
then.
