Zimbra Message Flags

Zimbra Messages have a "flags" attribute that describes the state of the message. This flags attribute is of type String and has a one character code which represents a state:

u -> unread

f -> flagged

a -> has attachment

s -> sent by me

r -> replied

w -> forwarded

d -> draft

x -> deleted

n -> notification sent


by default a message priority is "normal" otherwise:

! -> priority high

? -> priority low


Improvement

flags attribute should be of type uint and store bitwise flags. They are easier and faster to parse.


The following are the bit masks values that are used for the message flags attribute that's stored within the database.
