Hi,
In that case is there
A) any way to declare that all flags will be permanent, i.e. the server
will set any flag on any message
B) any sensible limit to the number or size of flags, or should the
server just stop using them when the limits reached.
I ask this because I can imagine a scenario where a user has a client
that is maybe buggy and keeps setting flags say \test1, \test2 ......
\test50
Then the user upgrades to a better client which doesn't understand all
these flags. Without killing the users mailbox and the meta data there
is no way to remove these flags. If there is an arbitrary limit in the
server as to the number of flags then the new client will break as it
cant set its own flags.
It might even be possible to cause a DOS attack on some servers by
running a loop
For n=1 to infinity
STORE +FLAGS (\MYFLAGn)
Has this been considered and if so what is the consensus on handling it.
