is rumored to have said:
tl;dr: Where do MailMate/Apple Mail store the flag color info for each
message?
All on the server, in IMAP flags/keywords: \Flagged, $MailFlagBit0,
$MailFlagBit1, and $MailFlagBit2
It is also possible to modify the header view to include "mailbox", in addition
to the "from", "subject", etc. fields. I did this with earlier versions of MM,
but it got broken sometime in the past year. I haven't tried to replicate, but
I found it very useful. If I have time again, I'll post
