After hours of debugging, I found that:

from django.forms.fields import email_re
email_re.match
('viewx3dtextx26q...@yahoo.comx26latlngx3d15854521645943074058')

will cause CPU to shoot up 100% and the process will hang forever.

Since this is the regex used to validate EmailField on forms, won't
this DOS a live site?

Where should I report this?

Is there a better way to validate an email address?
