1275	email validator does not accept single letter subdomains	volsung@…	Adrian Holovaty	"The validator for an EmailField does not accept email addresses which contain a single letter subdomain.  For example: iamnotauser@u.washington.edu is rejected.

I would suggest a patch, but I think I would need to be a cyborg to understand the regular expression in django/core/validators.py:
{{{
