make sure the currect directory is included in your classpath. or try this:
java -classpath %classpath%;. msgsend -o auduin@hotmail.com -M mysmtp.com auduin@hotmail.com

Thanks for your help again Kenneth.

That command seems to work, java -classpath %classpath%;. msgsend -o auduin@hotmail.com -M mysmtp.com auduin@hotmail.com

How do I set my system so I dont have to put -classpath %classpath%;.

CLASSPATH          C:\javamail-1.3.1\demo;C:\j2sdk1.4.1_03\jre\lib\ext\activation.jar;C:\j2sdk1.4.1_03\jre\lib\ext\mail.jar;

glad to know your problem is solved.
.; means you'll have to execute the java code.class in the dir where code.class is. and you'll need to start a new DOS windows in order to take the new env setting.
