Flags and tags are implemented in MM using IMAP's flags feature, so a 
shoddy IMAP server that does not support that feature requires that MM 
store any flags in the local cache for each message. This could be a 
HUGE sync project across clients, complicated by the fact that messages 
in the local cache may not be numbered identically on 2 different 
clients. It's not an impossible problem, but it's a very big task for 
first sync if you have a lot of messages and will always be slow. It's 
the price of 3rd-rate IMAP servers...
