(Thunderbird :: Address Book, defect)

User Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11

Steps to reproduce:

1- I had added the info about a contact manually in my personal address book
2- Later, the contact wrote me with the same email address, but using some capitals ([e-mail] VS [e-mail])


Actual results:

A new contact was added under collected addresses when I replied to the last email.


Expected results:

Since it's the same email address, it shouldn't have added a new entry.

OK, it touches part of bug 45946. However, I would like to work on the capitalized caracters only. I do understand an email address can be used by more than one, so it should be possible to have many entries with the same email.

However, there shouldn't be a new collected address for an address already available in one of the address books if it differs only by capitalized caracters. I'll try to fix this by myself and propose a patch.

My suspicion is that the Address book must be looking for a case sensitive string, while it should be looking for a insensitive string, It would solve part of the problem seen under bug 45946.

Of course, we could look for an insensitive email address. If found, we could either not add a new entry in the collected AB or we could also try to go further (is the name can be found in the firstname, lastname or nickname and samething for the lastname). This last solution would also clean some other duplicated address cases.
