Lower case Email Migration issues

[kmahelona]

Hi, we had a couple users with duplicate accounts because in one case they used upper case letters in the first part of their email, e.g. "My.Email@test.com" and "my.email@test.com".

I noticed this migration that would fail because of a lowercase equivalence change. But according to this stack overflow, the RFC doesn't have a restraint on case for the first part.

Can someone explain why 0006_emailaddress_lower.py was done?
