From and Subject lines blank after removing from Junk mailbox

Some users have been experiencing a problem when trying to retrieve messages from Mail's junk mail folder, in which some message header information seems to disappear.

Apple Discussions poster Aaron Harpole writes:

"When I drag a message out of the Junk folder into the Inbox, it goes into the Inbox, but the message loses its From field and Subject field. The Date received text is still visible."

Most affected users seem to be missing the "From" and "Subject" lines in the messages, though it is possible that other parts of the messages may be missing for other users. Some users have noticed that the messages with missing information regain it if they move the messages to another folder such as the trash and then move them back, though this is rather impractical to do every time a message arrives.

This problem is a classic example of a corrupted mailbox that should be fixed properly by rebuilding the user's mailbox.

Fix: Rebuild the affected mailbox To rebuild the mailbox, select the individual folder in the mailbox list (not a folder group), and select "Rebuild" from the "Mailbox" menu. This can take a while, depending on the number of messages in the mailbox.
