MailBoxes: All Messages	

Condittions: Flags>>Color is 5

Yes, I know 5 is not a color. But it is 4+1, or in binary 101, which is 
how the flag coloring mechanism works in order to be compatible with 
Apple Mail: 4 IMAP flags, one standard '\Flagged' and 3 $MailFlagBit[n] 
each representing a bit in a 3-bit color table.
