canonicalizeEmail removes spaces inside emails

Hi @riz0id, the whitespace in the grammar is the "CFWS" production. It is optionally allowed in local-part (the left hand side of the email) via:

   local-part      =   dot-atom / quoted-string / obs-local-part
   dot-atom        =   [CFWS] dot-atom-text [CFWS]
   dot-atom-text   =   1*atext *("." 1*atext)
   atom            =   [CFWS] 1*atext [CFWS]

The removal of CFWS when canonicalizing is due to the paragraph after these productions (my highlighting):

Both atom and dot-atom are interpreted as a single unit, comprising the string of characters that make it up. Semantically, the optional comments and FWS surrounding the rest of the characters are not part of the atom; the atom is only the run of atext characters in an atom, or the atext and "." characters in a dot-atom.

Note that removing spaces & comments from the email address is basically all that canonicalizeEmail does. So if you don't want this, you can instead use the isValid or validate functions and keep around the original ByteString.

Okay thanks.
