Email validator accepts bad email addresses.

[rkintzi]

Examples of invalid addresses accepted by validator: ala@ma.kota..pl ala@ma-kota-.pl

Better regular expression: (?i)^[A-Z0-9._%+-]+@[A-Z0-9]+([.-][A-Z0-9]+)*.[A-Z]{2,4}$

Hey there,

funny enough, we stumbled across this topic today as well. Some colleagues (thanks Matthias and Stefano) provided these resources which might help in enhancing Colanders email validation regex even more:

• https://github.com/django/django/blob/master/django/core/validators.py#L82
• http://ex-parrot.com/~pdw/Mail-RFC822-Address.html ;-)

Cheers, Andreas.
