JavaMail is the standard, but it is only a client, so you need to have a separate e-mail service to send mail. Asprin is a good implementation of a server.

EDIT: Asprin is a send only e-mail server. You can't use it as a full fledged POP or IMAP server. It just sends e-mail without any further third party (such as an ISP's mail service) dependencies (other than an internet connection). Unlike JavaMail, which requires you to have an SMTP server available to send e-mail for you (like from your ISP). If you need a full e-mail server, that can provide pop and imap e-mail, take a look at James.

Here is a list of java mail options, although most, like JavaMail, are clients, not stand alone solutions.
