According to Scott Kitterman <[email protected]>:
Honestly, I think l= is an idea whose time has passed (if it ever existed at all). We ought to just kill it using the simplest procedural mechanism available.
We can do an update to deprecate l= but I think that if we just adjusted our validation software to ignore l= the failure rate would be vanishingly low.
The ESP that was using l=1 has stopped. Ironport systems sign the entire body and set l= to the body length, so even if you ignore the l=, the signature on an unmodified message will still validate.
