RFC 5322 says (in section 3.2.2):

> Runs of (...) comment (...) that occur between lexical tokens in a
> structured header field are semantically interpreted as a single space 
> character.

Thus, some MUAs omit comments in From field when they render messages.

Since ARC does not need rewriting of From field as DKIM protection feature
does, it will be free from such trouble.
