Status: RESOLVED DUPLICATE of bug 377400

(Thunderbird :: Mail Window Front End, defect)

Description

[teaman]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3

When I select multiple email messages that are marked as UNREAD and delete them, they land in the Trash folder as UNREAD.  Good.
But when I select a single email message that is marked as UNREAD and delete it, it lands in the Trash folder as READ.  Not Good!
Please fix the later... I want msgs marked as UNREAD to remain UNREAD after I delete them. For those who want the msg marked as READ can press the M key before Delete if that is important to them. All other email apps I have used behave the same... deleting UNREAD leaves the status as UNREAD.
 

Reproducible: Always

Steps to Reproduce:
1. Select a single UNREAD msg
2. Delete it
3. Open Trash and find msg is now READ status.

To compare...
1. Select multiple (2+) emails marked as UNREAD.
2. Delete them
3. Open trash and find they are still UNREAD status.  (This is expected and good)

Actual Results:  
Single email msgs marked as UNREAD and deleted are changed to READ status in the Trash.

Expected Results:  
Single email msg marked as UNREAD remains as UNREAD after deleting it.
This would be consistent with deleting multiple UNREAD emails, which remain UNREAD when viewed in the Trash.
