Looking through my log which now has over 13,000 DKIM signatures from incoming mail, there's about 300 with l= and nearly all of those are from Cisco. Anyone from Cisco know whether you're doing anything with l= as opposed to just putting it in the signature? Related question: whether or not you sign with l=, does anyone have any software that does anything with l= other than use it to decide how much of the body to check? Anyone seen an MUA that uses it to manage message display? A spam filter that uses l= in its secret sauce? Any use of l= at all?
