	The ``tsift'' uses addresses in tokenized form, while
	``ssift'' does at first re-group tokens into a string,
	and then apply REGEX on them.

	For example:
		sample.address@there.somewhere
	tokenizes as:
		sample . address @ there . somewhere
	and you can't use ``tsift'' expressions, like:
		(sample\.addr.*)@(.*)
	to match it.  Rather you need:
		(sample)(\.)(addr.*)@.*
	or something of that style..

	With ``ssift'' you get a match with that first
	expression.
