Email addresses upper/lower case taken as two accounts

Hi Support,

We are on 7011 and have noticed that this may not be version specific but there are some strange instances of customers email addresses not being picked up as Contacts who are already approved in the system.

For example, each one of these instances seems to be taken as a different Contact

Name of person comes in as Email address comes in as

Fred Bloggs Fred.Bloggs@MyWork.com original
Bloggs, Fred Fred.Bloggs@MyWork.com name differs
Fred Bloggs fred.bloggs@MyWork.com name for email case differs
fred bloggs Fred.Bloggs@MyWork.com name case differs
Fred Bloggs Fred.Bloggs@mywork.com domain for email case differs

Can you look into this please, it's causing a large amount of confusion!!!

Cheers

Rich
