453240 - "Automatically add outgoing e-mail addresses to my:" option duplicates emails if email casing varies

Status: RESOLVED DUPLICATE of bug 129393

(Thunderbird :: Address Book, defect)

Description

[koonkii]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: 2.0.0.16 (20080708)

If i type an email to someone for the first time as "[e-mail]", it will store that in my address book.

Once the person replies, their email is formatted as "[e-mail]".
Because I am replying to the title-casing version of their email address, Thunderbird will add a duplicate entry under the same name and email address (but with different casing).

If this is intentional, please let me know so I shall place a feature request for something to find duplicates.

Reproducible: Always

Steps to Reproduce:
Enable "Automatically add outgoing e-mail addresses to my:" and set it to personal address book.

1. Send an email to someone not already in your address book in lower case.
2. If their email is configured to be used in a different case, reply to it.
3. Check address book and note the duplicates.
Actual Results:  
I now have 2 entries for the following email addresses:
- [e-mail]
- [e-mail]

Both with the same name, but differing case email addresses.

Expected Results:  
Detected that the email was already in the system and not add a duplicate.

Isn't this is a duplicate of Bug 58769?

Something similar was mentioned in comment #9, but the rest of it didnt make much sense of me.

moving stuff around and "CAB"s isnt necessary for this bug. its a simple case sensitivity check i would presume.
