title: open source mail clients in java
body: <p>Are there any open source email clients in java that you can recommend?</p>
  
  <p>Something that pulls in emails via pop, sends emails, stores sent emails, etc.
  Similar to what mozilla thunderbird does, but on build using jsp etc. for the web.</p>
  
  <p>(preferably web based, but would also be interested in desktop apps)</p>
