319156 - email addresses are CAPS-sensitive

Status: RESOLVED DUPLICATE of bug 129393

(Thunderbird :: Address Book, defect)

Description

[Rich Jones]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

the email addresses collected by the address book with the 'automatically add outgoing email' check box are caps-sensitive.
For example, if I have [e-mail] in my address book, and reply to an email from [e-mail], it adds another entry.

Reproducible: Always

Steps to Reproduce:
1.Have the auto-add feature turned on (in options - composition)
2.Have coworkers that insist on random capitalization in addresses
3.reply to email where the address has different caps than in the address book



Expected Results:  
The check against the address book should be caps-neutral when sending mail.

I'm not sure this is correct.
RFC says that the localpart has to be considered case-sensitive and the domain case-insensitive.
I know the case where multiple email addresses:
[e-mail] 
[e-mail]
[e-mail]
all exists and each point to a different account is unlikely to happen but it cannot be considered a rule.

Mozilla should probably ask wether it should consider the local part case insensitive or not (global preference or contact specific preference).
