This very basic function I was missing in this part of the Django Documentation when creating a custom MultiEmailField: http://docs.djangoproject.com/en/dev/ref/forms/validation/

# better solution proposed by KpoH:

from django.forms.fields import email_re

def is_valid_email(email):
    return True if email_re.match(email) else False

better solution

from django.forms.fields import email_re

if email_re.match(email):
    return True
return False

even better :)

from django.forms.fields import email_re

def is_valid_email(email):
    return True and email_re.match(email) or False

or

def is_valid_email(email):
    return True if email_re.match(email) else False

This is cleaner:

from django.forms.fields import email_re

def is_valid_email(email):
    return bool(email_re.match(email))

but a function is redundant, instead of calling it each time, one can simply do:

if email_re.match(email):
    ...

Just a note for those on Django 1.1.1 or higher having trouble getting this to work...

The location of the regular expression has moved to:

from django.core.validators import email_re
