296213 - Domain is autocompleted even if address does not exist in address boook

Status: RESOLVED WORKSFORME

(Thunderbird :: Message Compose Window, defect)

Description

[Mattias]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

When typing an email address, if the address does not exist in my address book,
Thunderbird will autofill "@mydomain.com" (whatever my domain is).  This is a
security problem in an organization where many users have similar aliases.

For example, I can end up sending an email to [e-mail] when the address is
really [e-mail] (or maybe something entirely different).  To me, it
looks just like [e-mail] is an entry in my address book.

I know Scott MacGregor said "That sounds like the correct behavior. We always
append the default domain if you don't provide one.", but please change this or
provide a way to turn it off.

As an aside, this "feature" has been dubbed "number one most annoying" by my
wife and the example above is not hypothetical.

Reproducible: Always

Steps to Reproduce:
1. Compose message and type start of email address without the @
2. Pause a short moment
Actual Results:  
My domain is auto-filled after what I typed

Expected Results:  
Nothing is auto-filled after what I typed

I downloaded the latest nightly build and I see that this has been fixed.  The
address turns red.  Beautiful!  Sorry about the clutter.
