I'm trying to mimic a particularly useful feature in Entourage, the show messages using these colors for read and unread messages. In Entourage you can simply set a preference to show unread messages as one color and read messages as another. Mail doesn't have this capability at all. You can set either the text color or the background color, but you cannot change this color depending on the status of the message (read or unread). The only thing I can do is either set the text or background color of all messages using rules, or set the text on unread messages to bold using preferences.
I found an Applescript that sort of does what I want:
tell application 'Mail'
set background color of (messages of inbox whose read status is false) to red--unread
set background color of (messages of inbox whose read status is true) to none--default read
end tell
However, this script will not work if you change 'background color' to 'text color'. It also changes the text color of the read messages in the preview pane to black when it runs the second part and I can't figure out a way to make the text a different color. I have a rule set up to set the color of text to a specific account, but the script overrides the rule.
Any suggestions on how this can be done?
