User set vacation with Start date Sept 30 and End date Oct 2, but  
Autoreply got triggered again near midnight  on Nov 1 (a month later)  
for certain senders on a different timezone.

The emails that triggered the late autoreply had "Received" headers on  
different timezones, e.g.

Received: ... Nov 1 (local timezone)
Received: ... Oct 31 (remote timezone)

The part of the sieve script that checks for Oct. 01-02 match is (simplified):

if header :regex "Received" "^.*(Oct)... {
    if header :regex "Received" "^.*([0 ]1|[0 ]2)... {
      vacation ...
   }
}

but this also matches emails on Nov 01 that have at least one Received  
header on Oct 31.
