I think we persist per sender, not per message... and we know proxy most of
|
|
that stuff, so I think a lot of users just show all messages... or we have
|
|
some complicated logic about when it's ok to show and when it's not which
|
|
is calculated on the fly and not exposed.
|
|
|
|
Not opposed to a standard, of course, just seems unlikely we'll use it.
