It's not possible to change the index format for individual emails in the index but you can colour different email entries differently.
Actually, it is. If you set index_format to a shell command that ends with a pipe, that Mutt will run that shell command for each message and use the output as the actual index_format. If you pass index_format expandos as arguments, Mutt will pass the expanded string. The shell command could then use that to emit different formats for different messages.
For example, I have a script called format_date, and have this in .muttrc:
set index_format="/path/to/format_date '%[%s]' '%<%s>' |"The script emits a different date format for each message in the index depending on how old it is: ' 6:41pm' if less than a day, ' Thu 6pm' if more than a day but less than a week, ' Jan 20' if more than a week but less than 30 days, and '01/20/11' if more than 30 days. See http://marc.info/?l=mutt-users&m=129556814118983 and the thread that leads up to it.
A different program could be written to examine the message flags in '%Z' instead of the time, and output different formats depending on those flags. The script in the message linked above could serve as a starting point, though the middle part where it's doing the date calculations would need to be replaced with flag comparisons.
I don't have time to experiment with creating a full solution for the original poster, but hopefully this will point someone in the right direction.
