If I specify any valid address in the 'from' part of sending a message I get an error: 08:08:18,115 ERROR [Engine] ----- Root Cause ----- java.lang.LinkageError: loader constraints violated when linking javax/mail/Address class at javax.mail.Transport.send0(Transport.java:155) at javax.mail.Transport.send(Transport.java:81) this occurs on my hosting company's server but not on my local one.

Search through FAQ's/Forums for your error string.

e.g. try http://www.jguru.com/forums/view.jsp?EID=1043426, where it says "...This happens when you have a version conflict between two .class files in separate .jar files.

Try searching your classpath for another .jar file containing another implementation (version) of the same and compare their dates. ..."
