I do not understand your example. (If there was an image, images are not allowed and are stripped by a mailing list server). The above line is a valid delimiter for parts of a mime multipart message. It ends with "--", so it is the final delimiter that ends the message. > > Curiously when I deleted the 'work' dir under tomcat it temporarily solved > the problem, allowing emails to be sent properly/correctly, but email > eventually became corrupt again, just hours later, and deletion of the 'work' > dir does nothing now (tried many times).

Sharing can result in side effects. 1. I think that when something weird happens but you can reproduce it, the fastest way is to try remote debugging. If Tomcat has been started with certain options you can attach a remote debugger. See https://cwiki.apache.org/confluence/display/TOMCAT/Debugging https://cwiki.apache.org/confluence/display/TOMCAT/Developing#Developing-Q1 Also do not forget to look for any strange errors in the log files. 2. When a library is shared by web applications, side effects are related to the broken life cycle of that library. Essentially they are likely to lead to a "Perm Gen memory leak". If you are new to this, it may be hard to explain, but some info is at https://cwiki.apache.org/confluence/display/TOMCAT/MemoryLeakProtection#MemoryLeakProtection-LogFactory and there are some presentations at https://tomcat.apache.org/presentations.html 3. A web application may illegally call System.setProperty() and thus affect global configuration. I saw some libraries doing so.
