Comment:
Replying to [ticket:27290 kyoki]:
> Django's {{{ validate_email }}}/{{{EmailValidator}}} doesn't properly
check the length of emails as defined in RFC3696. The local part should be
restricted to 64 characters and the domain to 255. The overall email
address length is restricted to 256 characters in RFC 2821.
The maximum length of an email address is 254 as in RFC 5321 it states
"The maximum total length of a reverse-path or forward-path is 256
characters". With two chars taken up, 254 is all we are left with.
