All cases where JSPWiki sends mail should allow authentication options in jspwiki.properties, since some email servers require authentication.

Personal preference: I would strongly recommend we do this as part of a container-managed mail resource configuration, rather than put passwords to things inside a file that lives in a WEB-INF directory. (That also suggests we need JNDI support for our mail service, but that's another story entirely...)
