De-lurking...I am not the experts you all are.


Should there be something said on how implementations handle deltas to the 
:time (or :seconds) window with respect to the previous response history 
database?  Does a change to the sieve remove/wipe the previous response 
tracking history?  I don't see any mention of that in RFC 5230.  For 
example...

Fred has a vacation rule with responses set for every 10800 seconds (he 
is in a morning meeting).  Wilma sends a message to Fred at 10:30 and 
receives a vacation response since it is the first message she has sent 
to Fred that day.  Fred gets out of his meeting and modifies his 
vacation sieve at 11:50 as he heads out to lunch with a :time now set to 
5400.  (He might or might not change the reason string.)  Wilma sends 
another message to Fred at 12:00 that would "match" her first message 
and not have caused a response under the original rule.  Does Fred's 
modification of the filter cause the sieve system to remove/wipe/clean 
its response tracking history and thus cause a new response to Wilma's 
12:00 message?

The reason I ask is that I see with user's being able to set vacation 
replies using seconds they might connect their 
Twitter/MySpace/Facebook/etc account status with vacation rules.  They 
update their ${SOCIALSITE} status and it updates their vacation sieve 
rule with their new status message. :) or :( depending our the side of 
fence you stand.  And I could see same thing in the IM/presence world, 
too.


If this is addressed somewhere sorry for wasting your time.
