If you want the anonymous login password to be more informative
	(and enable the use of picky ftp servers), set this to something
	reasonable for your domain, like [email protected]

	The reason why this is domainless by default is the
	request can be made on the behalf of a user in any domain,
	depending on how the cache is used.
	Some ftp server also validate the email address is valid
	(for example perl.com).
