Not sure what you mean by "xml file" - what would that be used for?
There are no specific mail servers for Java applications. JavaMail uses the standard mail APIs (SMTP, POP3, IMAP) and thus can work with any mail server that supports these (which means just about all of them).

You can use any standards-compliant mail server you want, James included.
