That might be a problem. My understanding is that duplicate
suppression records the message ID and recipient. Sieve vacation must
record the sender and a time interval of some sort. These are
different. Does `cyr_expire' treat them both the same? We have
people now who set vacation responder intervals longer than three
days. Is that not working?
