Email addresses in the literal form (where the square brackets are included):
are indicated as invalid by EmailField.
But the literal form is valid as per section 4.1.3 of the SMTP standard:
Sometimes a host is not known to the domain name system and
communication (and, in particular, communication to report and repair
the error) is blocked. To bypass this barrier a special literal form
of the address is allowed as an alternative to a domain name. For
IPv4 addresses, this form uses four small decimal integers separated
by dots and enclosed by brackets such as [184.108.40.206], which
indicates an (IPv4) Internet Address in sequence-of-octets form.
Also referred to in http://tools.ietf.org/html/rfc1123#page-57:
5.2.17 Domain Literals: RFC-822 Section 6.2.3
A mailer MUST be able to accept and parse an Internet domain
literal whose content ("dtext"; see RFC-822) is a dotted-
decimal host address. This satisfies the requirement of
Section 2.1 for the case of mail.
An SMTP MUST accept and recognize a domain literal for any of
its own IP addresses.
