Mailbox parser könyvtárak
- Apache James' MIME4J
- Javamail
- Aperture
Apache James' MIME4J is one parser and Javamail also can parse mail. I found
Javamail more intuitive, but have not tested either against a large mail set for
reliability and performance. (forrás)
You might have a look at Aperture (http://aperture.sourceforge.net).
It supports a fair number of mail sources including mbox and imap, I
think. (forrás)
