I omitted a detail, the application that adds multiple 'Re: ' is the same I'm working on, it was a test sending a message to my address with the same application and replying back multiple times.
As the application just calls reply() on the IMAPMessage, I see the prefix is added each time. That's how I think it works, I'll however give a look at the code again to be sure nothing more is done on the message. And I'll try your workaround too.
I'm not getting, though, your warning about always using utf-8: if I manipulate the message through JavaMail APIs, shouldn't it work with the set charset?
Thanks
M. R.

The code currently has this comment:

don't lose

isn't

>As a workaround you can use getSubject() on the reply message and
strip off multiple instances of "Re:" and use setSubject() on the
result. That will work fine as long as all the encoding information
is correct in the original message and you're willing to always use
utf-8 for the reply message.
