The documentation for model.EmailField states
Incompliance to RFCs
The default 75 character max_length is not capable of storing all
possible RFC3696/5321-compliant
email addresses. In order to store all possible valid email addresses,
a max_length of 254 is
required.
In fact, however, RFC3696 states of email address maximum length:
That limit is a maximum of 64 characters (octets)
in the "local part" (before the "@") and a maximum of 255 characters
(octets) in the domain part (after the "@") for a total length of 320
characters.
I note the same statement regarding the 254-character limit in the Release
Notes document for version 1.8.
