Fast Chemail

A Dart library to validate the email as it is defined in the HTML specification. The RFC 5322 is too lax (allowing comments, whitespace characters, and quoted strings in manners unfamiliar to most users) to be of practical use.

Also, has been considered the bounds defined in:

• SMTP :: Size Limits and Minimums

  • The maximum total length of a user name or other local-part is 64 octets.
  • The maximum total length of a domain name or number is 255 octets.
  • The maximum total length of a reverse-path or forward-path is 256 octets (including the punctuation and element separators).

  There is a great contradiction. The maximum total length of an email address is 320 octects:

  {64}@{255} => 64 + 1 + 255 = 320

  but the maximum total length of a reverse-path or forward-path is 256 octets. Addition, that is only the length of the email address because it may contain a display name, like first last <local@domain> and will often extend 320 octets.

  Now well, since the standard says: "to the maximum extent possible, implementation techniques that impose no limits on the length of these objects should be used", the bound to reverse-path or forward-path will not be taken.

  Such memo is not a standard else informational, so the correction done in the errata is not followed.
