The header canonicalization algorithm "simple" does not work properly. #182
Description
The following is about the sealing process.
In sealing process, we set the header canonicalization algorithm to "simple", then the subsequent ARC validation result will be fail.
We set "Canonicalization" in openarc.conf to "simple/simple" on the sending MTA.
Then we performed ARC sealing on an email using OpenARC, the verification result on the receiving MTA was fail.
The receiving MTA uses OpenARC for ARC verification.
